A home addition with Alliance Renovations runs from the excavation and foundation to the framing, roof, siding and interior finishing. Alliance started in 2008 as a concrete company, so the foundation work is done in house, and the whole project is tracked in a Buildertrend portal with payments in stages.
An addition is a small house joined to a big one. It needs a foundation, a structure that ties into the existing house, and finishes that match.
Alliance does the excavation and concrete itself, then the framing and finishing on top, so one company is responsible from the dig to the walkthrough.
An addition follows the order of a new home, joined to the one you live in.
A look at the house, the lot and what you need the space for, then a transparent quote.
Professionally done plans and the permits an addition needs.
Excavation, the foundation, then framing and roof, with payments in stages.
Siding, windows and the interior, then a walkthrough with the 3-year warranty explained and a 1-year follow-up.
What the City of Calgary asks for when you add on, with the City page for each one.
"All additions to your home will always require at least a building permit." The City puts the review at about 7 days.

“Highly recommend. Of all the companies that i contacted, Alliance was the only one that was able to construct a garage during the winter. They have done a beautiful job, on time and made the process painless. Colin, Ryan, Tim and the crew were amazing. They are super responsive and most of the time they would reply back to you within minutes. The Buildertrend app they use is also great. Don't hesitate to go ahead with them!”

“One of my friends recommended Alliance for basement development. They did all planning, provided professionally done plans and did all necessary demolition prior to starting renovations. The project was running online, we could see the schedule and updates of the schedule. If something was changing Ryan was contacting us right away and in general communication was fast and clear. Price was fair, we could see clear costs breakdown and total amount we payed was as agreed. We highly recommend Alliance for basement renovations.”

Every quadrant of the city, plus the communities around it.
Yes. Alliance started in 2008 as a concrete company and still does its own excavation and concrete, so the foundation for an addition is poured by the same company that frames and finishes it. One company is responsible from the dig to the final walkthrough.
Every Alliance client gets a Buildertrend project portal with the schedule, documents and payments on your phone. Nikolay wrote that he could see the schedule and its updates online, and Gus wrote that the team usually replied within minutes when he had a question.
Yes. Alliance offers project financing through Financeit, with a payment calculator and promotions that change through the year. Ask Malachy about the current options when you book your free quote and assessment, so the plan fits your budget before any work starts.
Alliance builds through Calgary winters, and several Google reviewers had their garages built in the winter months. Foundation and concrete work in the cold needs extra protection while it cures, so the schedule is planned on the assessment. Tell us your timing when you ask for a quote.
