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."

Dealers of Irpinia, Decor, Sub-Zero,Grohe, Kohler, Wolf, BlueStar and more! Member of the National Association of the Remodeling Industry, the National Kitchen and Bath Association, and the Better Contractor's Bureau.

"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!"

Home Building questions, answered by experts

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.

You can’t add home addition costs to an existing mortgage, but you can include them in a new mortgage if you take out a rehab loan. Rehab loans—FHA-backed 203k loans and conventional rehab loans—are for more than the value of a property, and the excess is meant to cover the cost of a renovation or home addition.

Tiny houses, often called tiny homes, need between 100 to 400 square feet, with the most common size being between 200 and 300 square feet. Tiny houses more than 400 square feet venture into apartment-size dwellings and may be considered more of a traditional house than a tiny home. The number of occupants, desired lifestyle, and furniture will all be major factors that determine the desired tiny house size.

In-law suite floor plans almost always include at least one bedroom, a bathroom, and a combination kitchen/living room area or separate spaces for the kitchen and living room. Larger in-law suites built in accessory dwelling units separate from your main structure can feature multiple bedrooms, dining rooms, and entertainment rooms in addition to the necessities.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.
