"I just had a sunporch replaced. Everyone was very nice and responsive. I'm happy with the work. The only suggestion I would have would be to ask about pet(s) in the house hold. Not every product is suitable for pets."

"Mr. Turner provided a design to convert the garage into a home that is visually appealing and kept costs down. He took care of all the permits and inspections (many). All the electrical, plumbing, drywall, insulation and heating work was well done - never a problem in passing inspections. The craftsmanship on the carpentry work is beautiful includes a walk in closet, laundry closet, window framing and baseboards. Bathroom was well thought out-every inch used. Many details I had not thought of Mr. Turner did (led ceiling lights, well placed heaters, lots of insulation added into the walls and attic). They also did an excellent painting finish of the entire house and floor installation. They left the home spotless to include cleaning out the heaters. Mr. Turner provided a detailed estimate with drawings after our first meeting and provided me an update after I requested additional work. This is a very honest and nice company to deal with. We will definitely call them in future for other projects."

"I am a rental property owner and live out of state and only had pictures of over grown trees and shrubs. Nathan was willing to work with me as I changed my mind about the scope of the job. He was always on site when he said he would be and did an excellent job trimming some shrubs and tree limbs. He sent pictures of the work that he did. My tenant was also pleased with the job. Nathan seems to be a very honest man and I recommend using him for yard work or whatever else you need help with."

"Craig and his team were awesome. They remodeled our bathroom for less than half of what we were quoted by the other companies. They did a great job and they were very efficient and fast to get the work done. I can't say enough about the guys at RCH Construction. My family and I are very grateful. Recommend 100%"

"From the onset, I had an AMAZING experience with Hugo Carpet Service. Mario, the Sr. Sales Manager, was a gem and he values effective and efficient communication. They came out and did an estimate, I asked a few questions and the responsiveness was on POINT. Additionally, I caused a scheduling mishap and they were able to accommodate my schedule changes. I also appreciate that they were able to install the flooring that I already purchased. The floor looks great and I have ALREADY (and will continue to ) recommend them."

"Blue Ridge Carpentry did the original deck work using wood, so it made sense to use them again to replace the wood with synthetic decking since they already knew the design of the deck and what would be needed. I was able to get a quote on materials from another lumber provider, but Kevin was able to get the same quote from a more local provider. The work included removal and carry off of the old wood decking material and replacement with the synthetic decking. The finished product looks great!"

FAQs for addition to existing structure building service projects in Martinsburg, WV

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
