In June 2022, Capstone Waterproofing performed an awesome job waterproofing my basement. 

Joe exemplified optimal professionalism. He was very patient with explaining the work to be performed and responding to all my questions. The team that was selected to provide my service, arrived on time and completed the job timely as promised. 

They left my basement as cleaned as before their arrival. I am very satisfied with the outcome of the job performed and I would highly recommend Capstone Waterproofing.

What Will Your Basement Finishing Include

Basement finishing is an extensive project with many facades. There’s a lot of work involved, but our complete service aims to take care of everything. Working with us means you won’t need anyone else to see your vision through. Here’s what our service entails:

Wall Framing

Wall framing in basements is an important step in basement finishing. It involves the construction and installation of framing, which acts as a support system for all other components of the basement, like drywall, insulation, and electrical wiring.

Wall framing aims to provide a strong and secure foundation for the entire structure, so you won’t have to witness foundation cracks or worse scenarios.

Wall framing is often done with pressure-treated lumber, but nowadays, many homeowners opt-in for steel beams that offer a much more reliable structure for your home. Most often than not, you’ll want your basement to be as resistant as possible.

Basement Waterproofing

Basement waterproofing is one of the most important steps in finishing a basement.

Waterproofing means ensuring your basement and foundation walls won’t succumb to water damage or long-term water-related issues like mold and mildew.

We specialize in waterproofing basements, and we’ve been doing it since our day one. We bring cost-effective and highly-efficient waterproofing solutions right to your doorstep; all you have to do is take advantage of them.

Our basement waterproofing service includes baseboard installation, waterproof paint, and egress window installation, and we can also install French drains to ensure your basement is good to go.

Basement Insulation

Basement insulation is a must if you want this space to be liveable. Basements are usually cold, and insulating it will ensure you’re keeping it at a comfortable temperature for you and your loved ones.

There are multiple materials to insulate your basement with. Some of the preferred options are rigid mineral wool boards, high-density polystyrene (Type IV), and polyurethane/polyisocyanurate boards.

At Capstone Waterproofing Solutions, we’ll show you the best materials in the market, and it’s up to you to decide whether you want to best or save some money.
