With over 20 years of experience, We take pride in quality craftsmanship. We are family owned, and believe in building long-term relationships with our clients by delivering honesty along with exceptional work. We pride our company on reliability, great communication, integrity, and customer service. We are experts in our trade and will do our best to keep you as educated as we can on your particular project. Give us a call today! We look forward to working with you!

"My project was to add a porch to the front of my antique house. I quoted the job out to 3 builders and found the prices all to be similar. Although Fiske Construction was very slightly higher I was impressed with the professionalism of the quote and Mike�s understanding of what I was looking for. I showed him a couple of pictures of the style I wanted and he immediately picked up the details that gave the look I wanted. Mike arranged for the permits and began work as soon as they were set. Mike�s work ethic is far better than many these days, he showed up early and worked hard all day, every day. I never felt that my job wasn�t his top priority. I added a couple of features during the construction , Mike gave me a very fair price on the additional work and arranged for the materials required. Mike is more than just a builder, he is a Craftsman. The fit, finish, and quality of the porch is top notch. I have had neighbors and strangers compliment me on what a beautiful porch and how it looks like it has always been there. It�s not an easy task to add to a house built in the early 1800�s and match the quality of workmanship and style for that period but Mike and his team nailed it, I could not be happier or ask for a single change for the entire project. If I need any building projects in the future I will definitely have Fiske Contruction do the work. These days with some pretty questionable contractors out there Mike Fiske is a shining star and a safe bet for any project you may be"

At Matriarch Construction, we take pride in our work. I promise to take extra care as if it were my own home. Let me show you why all my customers refer me to their friends and neighbors. We get the job done right the very first time, to eliminate any problems. We look forward to discussing your next project. We are women owned!!!

"Costs increased about 10% over estimate, work was well done and the final product was professional and well-built. Communication could have been better, the builder promised weekly meetings but that didn't happen. All in all, we were happy at the end of it all, and all questions were answered and all finishes to our satisfaction, which if you've ever worked with a contractor before, you know isn't a given. 5/5 would work with them again, the fireplace mantel and threshhold was particularly well done."

"Worst experience working with a contractor we have ever had. Lack of communication was astounding. Reached out to start the project on our tiny front lawn in June/July. Didn't start planting until mid October. Was told there were 5 jobs in front of ours. Ignored photos of exactly what we wanted. Finish product is passable at best. Would not recommend."

"Roberto’s did a fantastic job! I would highly recommend them. They were responsive and even came by on the same day to review the project. Jose was attentive to our wishes and made some insightful suggestions that we absolutely agreed with. His team came the very next day to remove the grass that had died during our exterior remodel. They thoroughly prepared the yard and took care not to disturb our existing plants. They approached the work thoughtfully and carefully. They then came back and did a masterful job of installing sod, cobblestone edging, and gravel installation into our planter beds. The yard looks amazing and we were thrilled with their work. I’d definitely bring them back to do any further work needed."

FAQs for addition to existing structure building service projects in Hanover, MA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
