"We acquired a condominium on the 2nd floor of a 2 family house in Arlington. MA. The existing hardwood floors were beyond repair and we wanted to add a 2nd bathroom. In addition we wanted to integrate the existing sun porch into the living room to more than recover the area lost to the new bathroom, and install central A/C. We had estimates from three other contractors before we met with Pedro from Crystal Renovations. His pricing was very competitive relative to the other contractors, but that was mostly due to the others trying to add work that we didn't want or need. Pedro listened to what we wanted and worked with us to accomplish it. From the very beginning of the project until the end Pedro was always responsive and answered, emails, texts, and phone messages in a very timely fashion. He and his crew and subs were a pleasure to work with and any issues that arose were dealt with in a calm and professional manner. Before and during the project Pedro made several design suggestions such as recessed lighting on the sun porch, shower stall light, and new bath layout that definitely improved on our original thoughts. In the end the project came in on time and with a very small increase to the original estimate despite some challenges he and his crew had to work through. The best part, though, is the absolute impeccable quality of the finished product. We highly recommend Pedro and Crystal Renovations and plan to use them again in the near future."

"James, Derek, Jose and the rest of the DiOrio team were great to work with. We hired DiOrio for a total full bathroom gut job - full demolition down to the studs and then renovation. As part of the process, we procured multiple quotes. James and Derek provided a rough estimate on the spot and then gave us the most transparency through the contract. They were quick to work with and get the contract sorted and signed. Pricing was fair and competitive. Once the project started, communication was great. Our project went on longer than anticipated as we added multiple things in the middle and worked with Boston's inspection process and they were always great managing the project, the contacts, subs, etc. They worked with at each step to ensure we were happy with how things were progressing. James was hands-on throughout the entirety of the project - from start to finish. His attention to detail is fantastic - particularly in the tile work, which was beautiful (despite us having a complicated pattern request). Toward the end of the project, he worked weekends and stayed late to we could get things done within a certain timeline. At one point in the project there was a hiccup from one of the specialists and Derek immediately reached out to us to ensure they would take care of everything. Totally seamless and I really appreciated that their long relationships with the people they worked with gave us security we wanted for the job as a whole. Totally trustworthy and thoughtful around all our kids, pets, home, and yard. They clearly put a lot of thought into the contract which includes all details, so be sure you understand what the finished product will be so there are no surprises. Always happy to answer questions - very helpful team. We've recommended to friends already and would definitely work with again"

"I hired Quality Construction (QC) to remodel my condo for sale. QC removed the old carpets and installed bamboo flooring through out living room and kitchen. The bamboo flooring came out beautiful. QC took the time to take care of every little corner to make sure there was no gap. Then I hired QC to remodel my kitchen, painted all walls and put in granite counter top.  The kitchen looks lovely. Then I hired QC to build a new stand up shower in my half bathroom great design he came up with on the first floor. QC installed ceramic tile 12 x 24 in my shower, install marble floor, cherry oak vanity black granite top, very nice medicine cabinet ,track lighting, painted all the walls.  All finished work came out marvelous. Next I hired QC to remodel my bathroom upstairs install new tub,marble floor, ceramic tiles 12 x 24 all around shower walls, cherry oak vanity black granite top,very nice medicine cabinet, track lighting n painted all the walls. QC workmanship very neat, very clean,take's the extra time that's needed for a great job.He is punctuate and reliable.  Not to mention that his price is very reasonable.  All my friends and relatives couldn't stop commenting how nice the remodeled unit looks like.  The remodeled unit looks so lovely that I almost changed my mind of selling it. Thanks to QC, my remodeled condo turns out so attractive that I sold the unit at one showing. I highly recommend QC for any remodeling work.  As a matter of fact, QC is remodeling the new home I just purchased and also putting in a two car garage for my new home now.  Be glad to tell you all about it later."

FAQs for major renovation multiple room service projects in Nashua, 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.
