"Perry Brothers Construction did exceptional work on our first floor family room renovation. They were prompt, professional, and priced appropriately. Every time we had a question, Bill would return our call/email/text within minutes. More importantly, they were honest and open about any changes that needed to be made to the original contract due to additions/subtractions to the original plan. We enjoyed working with them and would hire again."

"Great! The quality of his work is excellent. He is easy to work with and is very honest. He showed ingenuity in figuring out how to add a shower to a small powder room. This work was done over a year ago and both bathrooms continue to be a joy to use!"

"Planning: We met with three contractors and reviewed small, medium and larger options for our existing space. Ryan from Norman Builders won us over with his confidence, organization and no problem attitude. Of course we had concerns and questions, but it was clear he had worked in colonial houses before. What really won us over was his excitement to do something different with our space. From day one, you could tell every detail of this job mattered as this was a new way to design a traditional space. His timelines, pricing and execution plan was clearly laid out. As a GC, he organized everyone from; designer, permits, dumpsters, demo, electric, plumbing, painters, floors, ceilings, etc. He would do it all. The Job: Completely gut our existing kitchen and formal dining room. Remove a wall and install a steal support beam. He'd then move the kitchen to the old dining space and make the old kitchen a common area with built in desk, bench and bar area. The dining room would then be moved to our four season bonus room. Floors, wall, ceilings all came down. All new plumbing and lighting throughout the first floor. Execution: I mean, its funny to say, but we miss these guys. They practically lived with us for the summer. Couldn’t have been better with our entire family (kids and dog included) Everyone was so respectful of world climate (summer of Corona) and space. Of course you need patience with the process. Timelines were clear and the job finished slightly ahead of schedule. In the End: I mean, wow. When we looked at the blueprint on day one, we legit thought they shared the wrong plans. We couldn’t imagine everything we wanted would fit. They nailed it. It’s a dream space for our family and we couldn’t be happier. We couldn’t recommend Ryan Norman Builders any higher. We can’t wait to have them back to work on the upstairs next."

"We had a very small roof area need to be repaired. I sent request to multiple company to give a service quote. Few of them sent me replies and stated that they are too busy to come. Matt of MMP Consturction's contacted me promptly, scheduled an on-site visit and gave us a quote right away. The work was then scheduled and finished quickly. Matt did great job on reaching out, effective communication, and always arriving on-time. He also gave an evaluation on our roof condition. Also, Eric and Don did excellent job on finishing the project. They are all very polite, knowledgeable, and showed their professionalism. We would like to express our sincere appreciation to Matt and his crew. We are very grateful for having them arriving on-time before the winter storm to prevent potential damage of the house. From their react, we see a warm heart. No job is big or small, all jobs are equally important. Understanding the difficulties of others, for the people, been appreciated by the people. Thank you again for your high quality service. We definitively recommend MMP Construction Inc. to anyone for any related home project."

"Tim was fantastic. We live out of state and we felt so comfortable and confident that he and his staff could handle the whole house renovations. Tim went above and beyond his role of contractor. He understood the issues that we needed to get the house in shape and quickly to get it sold. We would not hesitate to hire him again."

"This was our 3rd project with the company. 1st was finishing the basement, which included a bathroom with a shower. 2nd - half bath remodel with an accent stone wall. And the most recent- master bath remodel which included adding a soaking tub and converting a linen closet into a shower. Dave, the owner, was very patient with me when I kept changing my mind regarding the design and materials till the very last moment when everything was already demolished. When we could not find the linen tower i envisioned , Dave custom built it! As a result, we have a beautiful spa bathroom with gray stone and wood accents. For all 3 projects we worked with Steve who does a great job! We are very pleased with the quality of work, work ethics and communication. We will definitely be using Dave again for our next project. Highly recommend!"

FAQs for major renovation multiple room service projects in Portsmouth, NH

Gutting a house involves completely removing outdated elements, including drywall, insulation, and fixtures, to reveal the underlying structure. This process is not only ideal for a complete remodel but is also critical in emergency situations such as flood damage where compromised materials must be replaced immediately. Contractors follow OSHA-approved safety measures throughout the demolition to ensure a secure work environment. This method provides a fresh, safe canvas for any future renovation.

Gutting a house is a cost-efficient choice. Home renovations cost between $20,000 and $88,000 compared to the cost to build a new house of $122,500 to $411,500. The reduced cost stems from retaining the existing structural framework while updating the interior. Factors such as house size, material quality, and labor directly influence the total expenses, making a gut renovation a financially smart decision.

The cost of demoing an interior is worthwhile because gutting a house creates a completely safe and refreshed environment by removing toxic or damaged materials like asbestos, mold, and deteriorated components. Professional supervision ensures all hazards are properly managed and health and safety standards are met. This process revitalizes the home's interior and can increase its structural integrity and overall value.

Remodeling a bathroom costs between $6,640 and $17,600, with high-end remodels exceeding $30,000. The final price is directly influenced by the quality of fixtures and design features—modern tiling, advanced plumbing, and custom details all add to the definitive expense. By selecting superior materials and design elements, homeowners ensure both functionality and a remarkable aesthetic upgrade.

Kitchen renovations range from $14,500 to $41,500 when the original layout is maintained. However, changing the layout by removing load-bearing walls or upgrading to premium appliances directly escalates costs, often adding over $1,000 per modification. These precise enhancements reflect the high-quality standards and result in a transformative and efficient upgrade.

A full gut renovation typically spans between four months and a year and a half. This period accounts for the permitting process, material procurement, and the overall scale of the project. Every phase—from demolition through rebuilding—involves careful planning and execution to meet deadlines while ensuring the work adheres to safety and quality standards.
