Construction & Home Renovation in St. Catharines: Tile, Bathroom, Marble & Stone Specialists
Looking for a construction company in St. Catharines that understands older homes? BGM Construction LTD is based just next door in Thorold, about 10 minutes away at 5 Swart Ln, and we bring our tile, bathroom, marble and stone work to homes across the Garden City. St. Catharines is the largest city in the Niagara Region, with a population of 136,803 (2021 Census), and most of its homes were built decades ago, so substrates, levelling and moisture need checking before any new finish goes down. That is exactly how we approach every renovation here: careful preparation first, then work that suits the house.

Renovation & Construction Services in St. Catharines
Every St. Catharines project below starts the same way: we look at what is underneath the existing finish before we install anything new. In a city where most homes predate 1981, that preparation matters, because substrates, levelling and moisture decide how long the finished work lasts. Choose a service to see more detail on its own page.
Tile Installation
We install ceramic, porcelain and natural stone tile on floors and walls in homes across St. Catharines, from Downtown semis to larger Grantham and North End family homes. Older floors often dip or flex, so we prepare and level the substrate first so large-format tile sits flat. The result is a surface that is easier to clean and suited to busy hallways, kitchens and entryways.
Bathroom & Shower Tile Renovation
Many St. Catharines bathrooms still have their original tub, tile and fixtures, and we renovate them with new tile, updated layouts and careful waterproofing behind the walls. Our shower tile work covers tub surrounds, walk-in showers and full wet-area tiling. We plan the tile layout around your plumbing and room size so the finished bathroom is practical to use every day.
Kitchen Renovation
A kitchen renovation in an older St. Catharines home often means working around walls and floors that are not perfectly square, and we plan for that from the first measurement. Our work covers tile and flooring, backsplashes, and the carpentry that ties cabinets, trim and finishes together. Whether it is a Merritton bungalow or a Glenridge family kitchen, we coordinate the trades so the room comes together in the right order.
Marble & Natural Stone Work
Marble and natural stone bring weight, variation and a finish that manufactured materials do not copy exactly, and we cut and set them for vanity tops, floors, showers and feature walls. In older St. Catharines homes we check that the floor structure and substrate suit heavier stone before installation. We also explain sealing and day-to-day care honestly, so you know what living with natural stone involves.
Brick & Stone Masonry
From brick repair and repointing to stone work for walls and exterior features, our masonry suits the brick homes found throughout Queenston, Facer and the older downtown streets. We match mortar and materials as closely as the existing work allows rather than covering character up. Sound masonry also helps manage water, which matters for homes that have already seen decades of Niagara weather.
Carpentry, Electrical & Plumbing
Renovations rarely involve one trade, so carpentry, electrical and plumbing are coordinated as part of our kitchen and bathroom projects rather than left for you to schedule separately. That covers framing adjustments, trim and built-ins, plus fixture and rough-in work where a layout changes. Having one crew coordinate these pieces makes older-home surprises easier to deal with openly if they appear.
Interlocking Stone: Driveways, Walkways and Patios
We build interlocking driveways, walkways and patios for St. Catharines homes in Port Dalhousie, Port Weller, Western Hill and beyond, on properly prepared and compacted bases. Good base work, drainage and edge restraints are what help pavers stay level through repeated freeze and thaw cycles. We will talk through paver styles and layout patterns at the quote stage so the finished surface suits your home.
Built for St. Catharines Homes: Most Were Built Before 1981
St. Catharines has 58,905 occupied homes in the 2021 Census count, and 19,160 of them were built before 1960, with another 22,675 built between 1961 and 1980. Together, about 71 percent of homes here were built before 1981, so most renovations in this city happen in houses with decades of history behind their walls and floors.
What older-home construction means for your renovation
Older construction is not a problem to work around, but it does change how a renovation should be planned. Floors may slope a little, walls may not be perfectly plumb, and bathrooms are often smaller than in newer builds, so layouts need measuring twice and honest conversation about what fits. Behind old tile there can also be tired plumbing, dated wiring or plaster and lath instead of modern board. We open up carefully, show you what we find, and talk through any extra work before it goes ahead, rather than covering surprises back up.
What we check before tile goes down
Tile is only as good as what sits under it, so preparation comes first on every older St. Catharines home. We check the substrate, whether that is existing board, plywood or an old mortar bed, for movement, rot and soundness. We check levelling across the floor, because dips and humps that old paint and lino hid will telegraph through large-format tile. We also look for moisture around tubs, toilets, sinks and exterior walls, since past leaks are common in homes of this age and need dealing with before new tile seals them in.
Heritage-sensitive work in older districts
Streets in Downtown St. Catharines, Port Dalhousie and other older districts have homes with original brick, trim and tile worth keeping where they are sound. Our approach is caution led: repair and match where that is practical, keep character features where we can, and discuss options with you before anything original is removed. If your property carries any official heritage designation, check what it covers with the City before planning exterior changes, because that status can affect what work is allowed.
Interlocking, Masonry and Exterior Tile That Survive Niagara Winters
Exterior work in St. Catharines has to cope with Niagara winters and with repeated freeze and thaw cycles through the cold months. Porous materials and trapped water are the combination that causes trouble, and most exterior failures start below the surface rather than with the visible finish.
Why freeze and thaw lifts and cracks exterior work
When water gets into joints, pores and the ground below a driveway, walkway or masonry wall and then freezes, it expands. As that cycle repeats over a winter, the pressure can push pavers up unevenly, open cracks in mortar, and break the bond under exterior tile. Poor base and poor drainage make it worse, because water has nowhere to go and stays in contact with the work. Older St. Catharines properties can also have settled or patched bases from earlier work, which is why the ground below needs checking before anything new is laid on top of it.
Base, drainage and edge restraints: how we build against it
Our interlocking and exterior work starts with excavation to a suitable depth, a granular base that is laid and compacted in layers, and bedding that is level before the first paver goes down. We think about drainage as part of the build, grading surfaces so water moves away from the house and away from the paved area rather than pooling on it. Edge restraints hold the field of pavers in place so it does not creep or spread at the borders, and joints are finished with sand that helps lock the surface together. None of this is visible in the finished photo, but it is what gives exterior work in this climate a fair chance of staying level.
Do You Need a Building Permit in St. Catharines?
Some St. Catharines renovations need a building permit and some do not, and the difference usually comes down to whether structure, plumbing, heating or the use of the space is changing. The summary below follows the City of St. Catharines guidance, and the City page is the source to check for the final word on your own project.
Projects on the City’s permit list that overlap with renovations
The City of St. Catharines says a building permit is required for additions, finishing a basement, adding or removing walls, altering plumbing or HVAC, structural changes, decks higher than 600mm, retaining walls, and sheds larger than 15 square metres. By contrast, cosmetic tile and flooring swaps on their own generally do not need a permit, while moving plumbing does. If your bathroom or kitchen plan shifts a wall, a drain or a vent, treat the permit question as part of the project from day one rather than an afterthought.
Inspections, electrical (ESA) and plumbing: who checks what
Work under a City building permit is checked by City building inspectors at set stages, and the permit is not closed until the final inspection passes. Electrical work is handled separately: it falls under the Electrical Safety Authority, known as the ESA, which has its own notification and inspection process. Plumbing changes sit within the building permit and are looked at as part of the City inspection stages. As part of a renovation quote we talk through which of these apply to your project so the right applications are made before work starts.
Basement suites and ADUs: the City’s pre-approved designs and grant programme
Finishing a basement is on the City permit list, and the same applies to creating a separate suite or an accessory dwelling unit. The City of St. Catharines offers pre-approved designs for detached accessory dwelling units, which can simplify the design side of a garden suite project. The City also runs a grants programme connected to this kind of housing, but funding availability changes, so check the City of St. Catharines website for the current position before counting on any grant money for your project.

Renovations for St. Catharines Landlords, Families and Small Businesses
Brock University area rentals: durability-first bathrooms and floors
Brock University has more than 19,000 students and about 2,800 residence beds, so a lot of students live in rented houses and apartments near the university and across the south end of the city. Rental bathrooms and floors take heavy use and frequent tenant turnover, so we lean toward durable porcelain tile, sound waterproofing and finishes that can be cleaned quickly between tenants. Landlords can talk to us about sequencing work between tenancies at the quote stage.
Aging in place: safer tiled bathrooms
For St. Catharines families planning ahead, a bathroom renovation is a chance to make the room easier and safer to use. Options include step-in or curbless shower layouts, slip-resistant floor tile, and blocking built into the wall framing so grab bars can be fitted securely where they are needed. We discuss mobility needs honestly at the site visit so the design suits the person using the room.
Small commercial tile and stone
We also carry out tile and stone work for small commercial spaces in St. Catharines, such as shops, cafes, salons and offices. Commercial floors and counters need hard wearing surfaces and neat, durable finishes that cope with daily foot traffic. Bring us your plans or book a visit and we will quote the tile, stone and related carpentry as one coordinated package.

St. Catharines Renovation FAQs
Do you serve my neighbourhood, and how far is St. Catharines from your base?
Yes. We serve every part of St. Catharines, including Downtown, Glenridge, Merritton, Port Dalhousie, Port Weller, the North End, Louth, Facer, Queenston, Secord Woods, Western Hill, Grantham and the Carlton Park and Bunting Road area. Our base is at 5 Swart Ln in Thorold, about 10 minutes away, so getting to your home for a quote visit or a day of work is a short trip.
Do I need a permit to renovate my bathroom or kitchen in St. Catharines?
It depends on what is changing. Cosmetic tile and flooring swaps on their own generally do not need a permit, but adding or removing walls, altering plumbing or HVAC, and structural changes do appear on the City of St. Catharines building permit list. If your plan moves a drain, a wall or a fixture location, assume a permit is likely and we will confirm the position during your quote.
How much does tile installation or a bathroom renovation cost, and what affects the price?
We do not publish set prices, because the honest answer is that cost is driven by your project. The main factors are room size, tile material and format, the condition of the substrate underneath, whether plumbing moves, how much preparation and levelling the room needs, and the fixtures and finishes you choose. After a site visit we provide a free, itemised written quote so you can see exactly what makes up the total.
How long will my bathroom be out of use?
That varies with the scope of work, and we will not invent a tidy number for you. A simple re-tile is different from a full renovation with moved plumbing, waterproofing stages and inspections, and older St. Catharines bathrooms sometimes hold surprises that add steps. During the quote we talk through the sequence for your bathroom, including which stages mean the shower, tub or toilet cannot be used, so you can plan around the work.
What happens if you find moisture, rot or old wiring behind the walls?
In homes built before 1981 it does happen, and the first step is that we show you what we have found and explain why it matters. We then agree the extra work and its cost with you in writing before it goes ahead, rather than burying it in the final bill. Electrical concerns are dealt with under the ESA inspection process described in the permit section above. No new finish goes over a known problem in your home.
Can interlocking handle St. Catharines winters?
Yes, when it is built for them. Niagara winters bring repeated freeze and thaw cycles, and water trapped in a weak base is what lifts and cracks paved surfaces. Our driveways, walkways and patios go in over properly prepared and compacted bases, with drainage planned in and edge restraints to hold the field in place, which is what gives interlocking a fair chance of staying level here.
Marble or porcelain for a shower or kitchen floor: which is right?
Marble is a natural stone, so every piece varies, it feels cool underfoot, and it needs sealing and gentler day to day care. Porcelain is manufactured, consistent in colour, hard wearing and lower upkeep, which suits busy family bathrooms and rental properties well. The right choice depends on the room, how it is used and the look you want, and we will talk through samples and care honestly at the quote stage.
Do you work in condos and student rentals?
Yes, we work in condos, houses and rented properties across St. Catharines, including rentals near Brock University. Condos usually involve building rules to respect, such as management approval and booking service elevators, so we factor that into scheduling. For student rentals we recommend durability first choices for tile and finishes, because those rooms see heavy use and regular tenant changes.
