Armstrong Waterproofing was incorporated in 1992. The owner, Shane Armstrong, has been in the field of waterproofing for over 30 years and has learned what works and what doesn’t. We take pride in our work and it shows in the very low number of service calls and outstanding customer referrals.

"The crew from Armstrong Waterproofing did a fantastic job of fixing our drainage problem. They were punctual and on time every day and even worked later that would be expected to get to a good stopping point each day. They were very careful not to damage any electric and water lines coming into the house during the excavation process. They excavated the ground to the footers on the outside of the basement wall, cleaned and applied waterproofing, and installed drain pipe both for a footer drain and for any downspouts. We have already noticed a big difference in our basement wall, even with the excessive rain this week. They offered sensible options for fixing our problem at a reasonable cost. We would highly recommend Armstrong Waterproofing."

"I worked with Richard Doyle directly. He and his staff are super nice, professional and honest. Richard has been doing wood working and remodeling for over 30 years and has a excellent reputation. I gave a "B" on price only because he sells and does quality work. So it is a bit pricey but you get what you pay for! So no - it's really a "A" but it is high end quality. I had this idea for a dream kitchen and he made it come true. I wanted "Zebra wood" frameless cabinets and he was the only reseller for the company that I thought could deliver the product that I wanted. Turned out the cabinet website pictures were not really what they sold as far as finishes. We spent months finding all the right manufactures to make the cabinets and do the veneers. He loved the challenge and really never charged me for the time he put in to get it right and it was right! These are not Ikea flimsy frameless cabinets. Mine have dovetail joints and solid wood with soft close hardware. 1963 kitchen and bath to 2030 modern. Love it."

I am a small growing business. I estimate each job personally. I hire labor depending on the size of the project plus I have very dependable subs. I take a down payment to start and a payment halfway through and then a final payment when project is complete.

"Seamus was recommended to us by our painter and we were blown away by the craftsmanship and care he took for our new home. He does high end looking work for reasonable pricing. Get on the schedule--you need to choose this contractor. We will be having him back to do some more custom work!"

Barndominium Builders questions, answered by experts

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.

A construction-to-permanent loan is the most common type of mortgage used to finance a house teardown and rebuild. These loans include financing for construction costs and convert to a long-term mortgage once construction is complete. Check the terms of the loan closely before beginning work—there are often restrictions requiring you to use licensed contractors for all work.

Start by researching local contractors with experience in cottage construction. Ask for references, check licensing and insurance, and review completed projects. Compare multiple bids, making sure each includes the same scope of work. A good contractor will communicate clearly, provide a detailed contract, and ensure all work meets code and safety standards.
