"BRW Construction is fantastic. Brian and his team did an awesome job building our farmers porch. Even with all the rain days they completed the project completely on time, they even came on weekends to make up for the rain days, that’s unheard of these days. They cleaned everything up after a long days work too, they are very neat. We are so happy with our build and are looking forward to another project with them. We couldn’t be happier with the way it came out, it’s beautiful! Thank you Brian! We love the porch!"

"Incredible customer service. Very thorough with great expertise. Our roof and gutters look amazing. Good price points and will not put a strong upsell or pressure to spend more. Very easy in terms of how they work seamlessly with the insurance company. Amazing how fast they put up the new roof and how great it looks. I give them the highest reputation and strongly recommend Bluebird Construction if you need a new roof!!!"

"My project was small compared to many other projects out there. And yet Josh and Straight Line Constitution were happy to take my business and made it a priority. There was some urgency to getting it done and they sent the right number of people to meet the deadline. And when unforeseeable complications arose they worked with me in order to find a solution that would achieve the goal of the project without extreme cost overrun. There are many contractors out there who will give you a wide range of quotes. If you want to go cheap then find someone who will do a half ass job for little money. But if you want it done right and you want it to last call Straight Line Constitution. The rates are reasonable the quality is top-notch and they're very friendly people to work with."

"I contacted 14 contractors over the course of 2 and 1/2 years to replace and paint exterior trim that was causing leaking into our unit and the unit below. No one else would take the job due to the degree of difficulty. They had to do the work on the back of the building using 60 foot ladder and 50 foot on the front of the building in frigid weather during late December and early January. It was not cheap, but reasonable due to the conditions to take on the job. They not only replaced and painted all trim where necessary, but prepped and painted all the trim on the back of the building and some extra on the front at no extra charge. Very pleased."

"Responsive. Respectful. Reliable. MRC Construction did an outstanding job with my new siding and gutters! This was my first big home improvement project. I set a budget, began the research and ultimately requested bids from four suppliers. MRC was the most competitive, offered the product selection and warranty I was looking for and their schedule fit mine. Rodrigo is professional and patient and answered all of my questions. Marco managed the onsite work flawlessly. From the first phone call to the last walk through, MRC Construction is FIVE stars. I highly recommend MRC Construction and will go back to them for my future projects."

FAQs for deck or porch projects in Alton Bay, NH

Northern white cedar is the most affordable cedar decking type and delivers exceptional value with low material expenditures. This option provides proven cost efficiency, meets essential durability standards, and is easy to paint or stain to meet your aesthetic preferences. By comparison, eastern red and western red cedar supply extra longevity and richer texture for a modest increase in investment.

Yes, cedar is a great choice for decking material. It offers a timeless look and natural resistance to decay and insect damage. Keep in mind that cedar requires regular maintenance, like resealing and cleaning, to keep it in top shape. With proper care, a cedar deck can enhance the appeal and value of your outdoor space for years to come.

No, cedar is not pressure-treated because it contains oils and tannins that naturally resist insect damage, rot, and decay. With regular maintenance, including annual cleaning and resealing every two to three years, cedar maintains its structural integrity and pleasing appearance for 10 to 15 years or more. Cedar’s natural durability, without need for chemical treatments, makes it an environmentally friendly option for outdoor structures like decks.

You should stain or seal your cedar deck every two to three years to maintain its appearance and longevity. This helps protect the wood from moisture, mold, and environmental damage, preserving its natural color and extending its lifespan. Regular maintenance keeps your outdoor space both attractive and durable season after season.
