"I was glad to find out that this John Betz and Sons also works in the Frederick area, where Im moving. They can help with many things around the house, but they were the only group I found who could fix windows. And they knew what they were doing! I didnt need to replace a crank on a casement window they found and fixed the problem, which saved me $$$. I will definitely keep there number for future projects."

"Valdovinos Construction built my 16'x16' Screened Porch and 12'x14' Deck, replaced an old Bay Window with a Sliding Door leading to the deck, and replaced a window and door with French Doors leading to the screened porch. It all turned out perfect and is beautiful. The materials and craftsmanship are top notch. I strongly recommend Valdovinos for your construction needs. This company was referred to me by several of my neighbors and I have referred them to my friends and co-workers. Everyone is ecstatic with the work completed by Valdovinos Construction."

"Best team EVER! New metal roof with solotubes and skylights, vents, etc, two room addition, car port, covered entrance patio, new deck, everything else brought up to code. Started on time, stayed on the clock, completed well within the expected calendar, everything solid like a rock. AND they were always smiling, happy in their work. Courteous, lovely workers, cleaned up after the job was complete.. Good pricing, too -- worth every dime. I'll never use another builder."

"They weren't able to do the project but were honest and straightforward about it. They spent a couple of hours helping me and home advisor find the right contractor who could do the work I needed to be done. It spoke volumes about their character and customer service"

HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.
Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.
You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website.
Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:
In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down.
Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
