Local questions
Building in St. Marys: Common Questions
Who issues building permits in St. Marys?
Most attached decks, covered porches and additions in St. Marys need a building permit from the Town of St. Marys. We prepare the drawings, submit the application and coordinate every inspection, so you never have to deal with the paperwork yourself.
Can you work on heritage homes?
Yes. We've renovated homes up to 150 years old and take care to preserve original character wherever possible.
Can you renovate a heritage stone or brick home in St. Marys?
Yes. We take care to keep original details where possible, and we'll check whether your property has any heritage requirements before work starts.
Do you build decks on riverside lots in St. Marys?
Yes. We design decks, stairs and footings around the grade on riverside and sloped properties.
Do you serve St. Marys regularly?
Yes. St. Marys is one of the towns we serve outside our main north-west area. Contact us to confirm availability for your project.
Can an addition match a heritage home in St. Marys?
Yes. We match proportions, rooflines and materials as closely as possible, and check for any heritage requirements on your property before design begins.
“We had our deck rebuilt from ground up and Patrick, Jeff and their team were excellent from first time meeting Jeff who came to do quote to the very end of the work being completed. They took care of everything ! The deck looks fantastic”
“We had to wait a bit but the wait was worth it. Our new front porch looks amazing. They even helped us out with a couple of side fences, something they don't usually do. I work awake nights and they were very accommodating to my schedule.”
“Amazing quality in construction for long term strength and durability. Patrick was very responsive to the plans we wanted for the deck and offered great solutions to some of the unknowns we had in the design.”
“It has been a few years since we had Quality Carpentry build a deck for us and looks just as good today as it did when it was first completed. The “quality” of their workmanship and the products they used plus their attention to detail proves that we made the right choice in choosing this company.”
