"I am in a condo association where we are responsible for our own decks - crazy I know. I am proud to say that my deck clearly stands out as the premium option. The materials are of high-quality. BRW gave me the option of using Trex and I couldn’t be happier. I was quoted a very reasonable price and they were very timely with the first visit, subsequent visit to start and completed the project VERY QUICKLY! I highly recommend BRW."

"Torin and his team did a wonderful job upgrading our original 1980s kitchen. He was flexible with its construction ‘quirks’ and helped me find materials within my budget. Kitchen remodel included cabinets countertops & lighting. Torin is detailed and thorough. He shows up on time, is clean and personable. Throughout the project, he took on smaller fixes including replacing my bathroom faucet, fixing the drafty front door & hiding the TV cable wires behind the wall. Overall very satisfied with his work. "

"We hired Jim Longden in 2023 to install flooring in our dining room, kitchen, and downstairs bathroom. He also installed a vanity, sink, and toilet for us. He claimed he was capable of doing that work and we hired him in good faith. He made some egregious errors which caused flooding and water damage that was discovered in 2024. Uber our toilet the blocking was gone and the hole under our toilet was too big. He also never sealed the toilet in the floor so you could just wiggle it around in the bathroom floor! A professional contractor would never make these mistakes. Water leaked underneath our bathroom, kitchen, and dining room floors and they all had to be torn out. We had to pay for the repairs out of our own pocket so we are currently $30,000 in debt. We are still fighting with his insurance to pay for this! DO NOT HIRE THIS MAN. "

"Two stars because the work was eventually finished, but they left work partially completed with a dormer exposed to rain for several weeks. They also sent a finished work certification before the work was done to ask me to certify that it was complete. The owner discounted the work slightly, but it was a bad experience that delayed the house renovation and I do not recommend this contractor to others"

FAQs for deck or porch projects in Amherst, NH

To maximize your budget, compare quotes of several builders that fit within your specifications. Don’t be afraid to draw a wider geographic circle if the contractor is willing to travel without charging more. But affordability only matters if you get a quality deck out of it.

Cutting corners or simply finding the cheapest pro could result in significant problems. The materials used may be cheap and rot quickly. The support the surface provides might be unstable and dangerous. Always consider the long-term costs and benefits of quality work. Paying less upfront may actually be more expensive if you consider the cost of repairs.

Deciding on which materials you should use depends entirely on the type of deck you’re looking for. Composite works well for a simple surface exposed to harsh elements, while concrete is the standard choice for many patios. Your decking material options can range from wood to aluminum. Learn about the pros and cons of these materials to make the right decision.

You can build a deck during any season, which is why choosing the right time for this project depends on your preferences:

  • Spring: get your deck ready in time for landscaping and to enjoy it throughout the warmer seasons.

  • Summer: use spring for the planning process, then get the project ready before it gets cold out.

  • Fall: Limit turf or landscape damage by building once most plants begin to recede.

  • Winter: make the excavation process easier, thanks to cold and firm ground.

Many deck builders prefer winter, which is also the season with the shortest waiting queues. Still, other seasons are far from impossible for this type of project.

Expect a thorough examination of the space, and the development of a project schedule. Delivery of materials might already have occurred or could be planned at this point.

Additional research about working with deck builders can help you understand what to expect from experts, and what they expect from you.

Make sure the site of the deck or patio is clear of any landscaping and debris. The contractor will also call a utilities locator service to mark power, water, cable, and other services around the area where they will be digging. The cleaner the area your builder has to work with, the more quickly they can get started. Make sure they have space to park any construction vehicles. Find a dry space for materials that might need storage during the install. Finally, ensure clear access to the site through your house or property.

When it comes to the DIY vs. hire a pro decision for your deck, the answer tends to be clear. Only take it on yourself if you have significant expertise and experience. Without either, you risk building a faulty exterior space, leading to injury risks. Projects built without necessary expertise also break more quickly, making them more expensive in the long run.

If you do want to take on decking as a DIY project, be sure to do your research. Learn about installing the posts and footing for your framing. Understand how to lay decking boards and build the railings and stairs you need for access and security.
