Excellent service

Two words: human touch. I felt that Billdr was really invested in the project. You could tell that the project was important to them and that we weren't just another number. We needed that support throughout the construction work. We're very satisfied, very happy. It's really nice, it's bright. We've achieved our goals.

Backyard renovation

Backyard Renovation Success!

We used Billdr to renovate our backyard. Their services were highly valuable. They put together a clear scope of work that both us and the general contractor could understand, making communications way easier. They also helped validate our budget, so that we knew exactly what to expect in terms of costs and timeline.

Work with Billdr-certified, licensed general contractors in Ajax

Finding a licensed and insured general contractor with a track record of high-quality work is essential to the success of your renovation project. We have a rigorous process to vet and certify every general contractor in our professional network. 

To become certified, general contractors must possess a valid building renovator license (where applicable) and WSIB clearance certificate, commercial general liability insurance of $2,000,000 or more, a minimum of two years of relevant experience, and references from recent clients

Beyond the paperwork, the Billdr team meets with each contractor on active job sites to observe the way they work and make sure they are a good fit for the Billdr network. As we get to know our partners, we build strong trust relationships.

If your renovations do not involve major structural work (e.g. demolition of a load-bearing wall to create an open space) or displacement of plumbing and gas pipes, prices will be lower. When you choose premium materials the costs will go up.
