We work in finished homes with care. Floors, walls, trim, and surrounding areas are protected so the project feels controlled from start to finish.
A good result is not just about the product. Proper measuring, alignment, shimming, insulation, and sealing all affect comfort, energy performance, and long-term reliability.
Replacing drafty windows and aging doors can make rooms feel more stable in winter and summer, with fewer cold spots and less temperature swing near openings.
The goal is not a rough install that looks acceptable from a distance. It is a clean, integrated result that suits the rest of the home.
Older openings, settled homes, and finished interiors require judgment, not rushed production work. We approach replacements with that in mind.
New windows and doors change how a home feels immediately, both from the street and from inside. Cleaner sightlines and better proportion make a visible difference.
If certain rooms feel colder, especially near windows or exterior doors, the issue is often failed seals, worn components, or older glazing that no longer performs well.
Aging units can allow heat loss in winter and unwanted heat gain in summer, forcing your HVAC system to work harder than it should.
When moisture gets between panes, the sealed glass unit has failed. At that point, performance and clarity are both compromised.
Windows that stick, fail to lock properly, or doors that drag, swell, or leak air are no longer doing their job well.
Thick old frames, worn finishes, or dated door styles can make the whole house feel older than it is. Replacement is often one of the fastest visual upgrades.
Better glazing and tighter sealing can noticeably reduce outside noise, improving comfort in busy neighbourhoods or near main roads.
Proper fit starts before installation day. Good measurements reduce adjustment issues, improve sealing, and help the finished result look intentional.
The perimeter around a new unit matters. Insulating and sealing the opening properly is part of what helps the system actually perform.
Even a premium door or window can look poor if the interior finish is sloppy. Clean lines and clean transitions are part of the final result.
Not every opening needs the same solution. Front entry doors, patio doors, basement windows, and primary living space windows each have different priorities.
In colder climates, glazing, air sealing, and installation quality matter. The right setup should improve comfort without creating unnecessary complexity.
A replacement project should not leave the surrounding area looking beaten up. Clean work habits matter as much as the install itself.
Garage doors are reviewed as part of the home’s exterior opening package, alongside entry doors, windows, trim, capping, weatherstripping, and curb appeal details.
We can review damaged panels, noisy operation, opener compatibility, weather seals, tracks, springs, and trim conditions before deciding whether repair or replacement makes sense.
Door colour, panel style, glass, insulation, exterior trim, and adjacent window or entry door finishes should work together so the front elevation feels consistent.
A popular choice for durability, low maintenance, and strong value. Modern vinyl systems can offer excellent thermal performance when paired with good installation.
A solid standard for many homes, offering improved insulation and better comfort than older single-pane units.
Often worth considering in Ontario for better insulation, improved sound reduction, and stronger comfort near large openings or exposed elevations.
Entry doors affect first impressions, security, air sealing, and daily use. A well-fitted door should feel solid, close properly, and look right from both sides.
Large glazed openings need careful installation to operate smoothly, seal properly, and avoid a bulky or poorly integrated appearance.
Many homes are not perfectly standard. Replacement work often requires solutions that suit the actual opening and the finished condition of the home.
Our sourced vinyl window systems are designed for Canadian weather, with low-maintenance vinyl frames, insulated glazing options, and configurations suited to retrofit or brick-to-brick replacement.
Depending on the room, budget, and exposure, homeowners can choose double-pane or triple-pane glass with Low-E and argon options for better comfort.
White remains common, but modern black windows, custom colours, painted frames, brickmoulds, grilles, and glass options can change the look of the whole exterior.
Product performance depends on the install. Shimming, insulation, flashing, caulking, trim, and exterior sealing decide whether the new window actually performs.
Some homes suit retrofit replacement, while others need a fuller brick-to-brick approach. We review the opening, frame condition, trim, exterior finish, and water path before recommending a method.
Supplier warranty and workmanship details should be clear before work starts, including glass, frame, hardware, painted finish, installation scope, and what is excluded.
The quote should say whether the work is retrofit, full frame, brick-to-brick, door slab only, complete entry system, or patio door replacement.
Glass, Low-E, argon, double or triple pane, spacer, frame depth, colour, grilles, hardware, screens, locks, brickmoulds, and door glass should be clear.
Customers care about drywall, casing, stool, jamb extension, paint-ready trim, caulking lines, and whether the room looks finished after installation.
Caulking alone is not the whole story. Flashing, sill condition, slopes, brickmoulds, drainage, and exterior cladding details affect long-term reliability.
Product warranty and installation workmanship should be separated clearly so the homeowner knows who handles glass, hardware, leaks, finish, and service.
We can use strong supplier product lines while keeping the homeowner’s experience with Strataline: product selection, ordering, installation, finishing, and support stay coordinated through one contractor.
Foggy glass, broken hardware, rotten frames, drafts, and poor insulation point to different fixes. We separate simple repairs from full window replacement before quoting.
Competitors often use these terms loosely. The right method depends on the old frame, rot, water staining, interior casing, exterior cladding, masonry, and the finish you expect.
A slab swap can work only when the existing frame is square and sound. A prehung entry system is usually better when sealing, alignment, threshold, or frame condition is the issue.
Low-E coatings, argon gas, warm-edge spacers, double or triple pane glass, frame depth, and weather seals should match the exposure and room use.
Price changes with size, style, glass, colour, installation method, trim work, access, second-storey work, structural changes, and old-unit disposal.
A clean project includes casing, jamb extensions, caulking, paint-ready trim, exterior capping or brickmould, cleanup, and a final operation check.
Casement, awning, picture, fixed, hung, slider, end vent, bay, bow, basement, bathroom, kitchen, bedroom, and living room window choices are covered here in one place.
Front doors, side doors, rear doors, garage man doors, patio doors, garden doors, French doors, sidelites, transoms, glass inserts, and locks are all addressed.
Brick-to-brick, retrofit, full frame, stud-to-stud, slab-only, prehung, casing, jamb extensions, brickmoulds, flashing, capping, and caulking are explained in plain language.
Drafts, cold rooms, outside noise, UV, condensation, fogging, failed seals, Low-E, argon, triple pane, laminated glass, and weatherstripping are covered for Ontario homes.
Permits, egress, structural changes, condo approvals, rental properties, commercial spaces, property managers, lead times, and phased replacement are included.
Warranty, service, adjustment, maintenance, screen care, caulking inspection, hardware, and what to do after installation are included so the homeowner is not left guessing.

Popcorn ceilings
WOW! Just WOW! Max removed all the popcorn from our 1800 sq ft town home, repainted from top to bottom plus did some carpentry repairs on our floors…and the final result is spectacular! But just as important, he made the entire renovation painless for us: not only was the process completely dust free and mess free, but Max also moved ALL the furniture and pictures himself (no help from us at all) then put EVERYTHING back together the way it was. We literally walked out of our home before he started and then walked back in a couple of weeks later to a beautiful brand new home with everything in the exact same place as it was beforehand. Renovating doesn’t not get better than this!!!

Stairs & railings
Max and his team at Strataline have done multiple home improvement projects for us, including stair refinishing, popcorn ceiling removal, new flooring and interior painting. From the start their team was professional and punctual. The stair refinishing completely transformed the look of our home. The popcorn ceiling removal was done cleanly and efficiently with great attention to minimize dust and mess. The team delivered on time and with no surprise budget increases. I would definitely recommend Max and his team at Strataline.

Popcorn ceilings
The Popcorn removal was excellent and a very clean process. They also transformed our stairs from boring oak to a much more modern look. They handled repainting of the whole house and replacement of old tile floors with a beautiful new one. There were many additional small tasks which they handled very well. They have design skills if you need them. The house looks great. Very talented and reliable people. I should also say they are very professional providing detailed quotations and billing.

Popcorn ceilings
This is the second time Max has done some work at our home. The first time was to remove popcorn from our hallway ceilings. We were so very impressed with the results and it was truly dust-free. This time Max removed wallpaper and prepared those walls for painting. He painted several other areas as well and sanded and reapplied urethane on all our new doors. And again it was dust-free! He and Galina are superb craftsmen. Their attention to the smallest of details speaks volumes of the pride they take in their work. A quality that is difficult to find these days. We highly recommend Strataline. Thank you Max and Galina. We will be calling again for the next project. Ilene and Mario, Maple

Painting
My wife and I used the services to paint our entire condo, including the ceilings, walls and baseboards. In addition, they installed new kick boards under our kitchen island, counters and in the bathrooms. The quality of the painting was excellent, but what really stood out was how clean they kept everything. Their dust control was outstanding, and they left our condo spotless at the end of the job. We truly appreciated the care they took to protect our home throughout the entire project. We highly recommend Strataline and will not hesitate to use their services again.

We had great experience working with Max. He was very attentive to all our concerns and requests, easy communication and quality of workmanship is outstanding! Special care was taken to keep our living area clean and dust free as renovations were taking place. We’re very pleased with end result and will definitely recommend him!
FAQ
We replace windows, exterior doors, patio doors, sliding doors, garden doors, entry doors, storm doors, trim, casing, caulking, insulation, flashing details, hardware, and related interior and exterior finishing.
Signs include drafts, condensation between panes, rot, damaged frames, broken seals, difficult operation, poor locking, water stains, ice buildup, exterior decay, loud street noise, and high heating or cooling discomfort.
Retrofit installation keeps much of the existing frame and installs a new unit into the opening. Full-frame replacement removes the old frame down to the rough opening, allowing better inspection, insulation, flashing, and trim correction.
Retrofit can be appropriate when existing frames are sound and budget is tight. Full-frame replacement is better when frames are rotten, leaking, out of square, poorly insulated, or when you want maximum glass area and a cleaner long-term result.
Yes, when they are properly selected and installed. ENERGY STAR windows can improve comfort, reduce drafts, limit heat loss, reduce condensation risk, and help with energy performance, but installation quality matters.
Vinyl is common and low maintenance. Fiberglass and composite frames can offer strength and stability. Wood offers warmth but needs maintenance. The right choice depends on budget, opening size, design, energy goals, and maintenance expectations.
Glass choices include double pane, triple pane, Low-E coatings, argon fill, laminated glass, tempered glass, obscure glass, and sound-control options. The best package depends on sun exposure, noise, privacy, safety, and energy goals.
Triple-pane glass can improve comfort, sound reduction, and cold-weather performance, especially on exposed walls. It costs more and weighs more, so frame, hardware, and opening size should be reviewed.
Condensation usually comes from indoor humidity meeting cold glass. New efficient windows can make humidity more visible because they reduce air leakage. Ventilation, humidity control, blinds, and room airflow all matter.
Yes. Moisture or fog between sealed panes usually means the insulated glass seal has failed. That is different from room-side condensation and often requires glass or window replacement.
Yes, but glass type, air space, laminated glass, frame quality, installation, and air sealing all matter. No window makes a room silent, but the right package can noticeably reduce street noise.
Like-for-like window replacement often does not need a building permit, but changing opening size, structural lintels, egress requirements, heritage properties, condo rules, or multi-unit buildings can change requirements.
An egress window is an emergency escape window that must meet size, opening, height, and access requirements for certain bedrooms or basement spaces. Changing basement windows should be reviewed carefully.
Yes. Basement windows may involve concrete, wells, drainage, security, egress sizing, insulation, and interior trim. Moisture around the opening should be checked before replacement.
Entry doors need accurate measurement, swing direction, sill height, weatherstripping, lockset, threshold, insulation, frame condition, sidelights, glass privacy, exterior trim, and interior casing review.
Steel is durable and cost-effective, fiberglass resists dents and can mimic wood, and wood is beautiful but needs more maintenance. Exposure, security, style, and budget guide the choice.
Yes. Patio doors need careful measurement, sill support, drainage, flashing, rollers, locks, screen condition, glass type, and interior/exterior trim. Poor sill work can cause leaks.
Many window replacements can be completed in a day or two depending on quantity and finish work. Entry doors and patio doors vary with frame repair, trim, sill work, and exterior conditions.
Clear window areas, remove blinds or curtains where needed, move furniture, protect valuables, provide driveway access, and keep pets and children away from work areas. We plan protection before removal.
Yes, with planning. Openings are handled one at a time, work areas are protected, and sealants must be appropriate for temperature. Severe weather can affect scheduling.
Leaks can come from failed caulking, poor flashing, rotten frames, missing drip caps, bad sill slope, masonry cracks, roof or siding issues, clogged weeps, or condensation mistaken for leaks.
Yes. Gaps around frames should be insulated and sealed carefully without distorting the window. Air sealing, shims, flashing, foam choice, and trim details affect performance.
Exterior caulking should bridge the right joints, adhere to clean surfaces, allow movement, shed water, and be compatible with the materials. Caulking over failed or dirty joints does not solve leaks.
Yes. We can coordinate interior casing, jamb extensions, stool, apron, exterior brickmould, capping, trim repair, paint, and caulking so the installation looks finished.
Look at product warranty, insulated glass warranty, hardware warranty, finish warranty, labour warranty, exclusions, transferability, condensation language, and what happens if installation causes an issue.
Compare product series, glass package, installation method, full-frame vs retrofit, trim scope, disposal, insulation, flashing, caulking, warranty, payment terms, and whether finishing is included.
