Residential Improvement Specialists








Double Check Builders has the ability to handle all your building needs. Whether you need a small room addition for a new child or a large mother/daughter apartment for a relative, we can take your current floor plan and turn it into something that meets your needs and exceeds your expectations.
Many people ask if we "do it all" and the answer is YES! When you talk design with us, the sky is the limit. Do you want a crawlspace for added storage and ease of repairs, or a slab to save some money? Do you need a full basement for extra storage room, or a future office? When Double Check comes to your home for your free estimate we find our what you need, but also what you want or dream about. Many times those dreams become reality. Because we handle the expediting of paperwork with all the towns in both Nassau and Suffolk, we can help reduce costs and are able to give you more.
Do you want a kitchen added to your home, or a bath off your master bedroom? How about a fireplace added in your living room? They don't only offer a spectacular ambiance but also help you save on your heating costs because of how efficient they have become.
If you fell in love with a house when your family was smaller and now you need extra room, why not add a second floor or dormer to expand your current living space? When we design second floors, our goal is to build the project with minimal invasiveness in the existing living quarters. We have the ability to "go over" the existing structure with engineered lumber that gives us ultimate control when it comes to layout and design. We give you access and consultation to a NYS licensed Architect and as a result, we are able to maximize your space while keeping the design functional with exceptional curb side appeal. This gives you the greatest opportunity to get exactly what you want from your project and to bring the project to completion within budget.
While we're building your second floor or addition, why not change your current siding and completely transform your home's look? You can add stone to your house or get creative with siding and trim colors. Add a Portico for style and functionality to keep you dry on those rainy days.
In addition to second floors and additions we also do other projects such as porticos, finished basements, windows, roofing, and much, much more!
