We are a small family owned business and we are all dedicated to give our customers the best work possible not only just for our pay but its our personal name also which gives us a lot of pride. As the owner I am personally hands on working on your project not just sending workers.

"Jeff and his crews delivered on time and on budget. I was advised each day of the activities that were going to take place the following day. All workers were pleasant and responsive to any needs. Each day prior to leaving the job site everything was cleaned up, equipment and materials stored neatly, and any trash removed. The quality and craftsmanship were excellent."

"Extremely disappointed with this company. They do not stand by their guarantees. Did install shower in one day. Was not provided with the shower head I ordered. Calking and trim work was very sloppy. Went through the shower wall into my bedroom, did sparkle wall and left it. Shower doors have leaked and was finally told six months later that there is nothing they can do to correct the issue. Originally quoted $24,000.00 for the walk on shower, eventually agreed to $11,500.00. Completely dissatisfied with my shower. Once they get their payment, they are done."

Here at Best Homes, our company is based on the belief that our customers' satisfaction is of the utmost importance. Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez

"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

FAQs for addition to existing structure building service projects in Knoxville, MD

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.
