"Pleasure to work with. Price was easily cheapest. Endlessly impressed w/ knowledge & attention to detail. Scheduled appointments (at no cost) to see available stock at hardware stores. Picked up all materials at no cost. Finished job early & on budget despite running into unforeseeable challenges (eg. cheap plastic pipes burst, but they bought and installed new plumbing for no additional charge. Also, after accidentally stripping off finish from wood floor, refinished it at no cost). Rare professional dedicated to ensuring a good experience & high quality, at low cost"

"The owner came out very late at night on a holiday for our emergency leak and stayed very late to fix it. Would highly recommend"

"I have used Navid's Construction for several projects at two homes we've owned. The first job required replacing front porch posts on a vintage, 1928 Sears Craftsman Bungalow. We were selling the home and needed to replace a rotting wooden structural porch post having architectural design features that I was adamant about replicating exactly as the original construction. Navid was able to completely reconstruct both posts with their added design features and do that work FLAWLESSLY!! I was incredibly pleased with the final results that he was able to accomplish within one day between him and his crew. This was all done, btw, within one week of closing with our buyer in advance of the sale of the home! A bit harrowing for me, but no problem for Navid! He also tackled reinforcing a joist and taking care of some termite damage. I engaged him again for another home of ours to reinforce a termite damaged joist and repair a 2nd floor drain. Success on all fronts. Total pro; use NAVID!!"

"We negotiated with Alex the terms and conditions of remodeling two bathrooms including budget and timeline and we were very pleased with the quality of the work and how well the budget and timeline were achieved. Highly recommend him."

"Excellent diagnosis of the work needed. Complete review of external meter and cable rigging needs, upgrade to new panel inside the house and corresponding grounding under the house (crawl space). Very reasonable pricing as well. I’ve hired D&G Remodeling for the work. The Lord is good! Thank you Angi!"

"This was the third project Munoz Construction completed for us and we couldn’t be happier with the result. This project was mainly focused on renovating our primary bathroom along with exterior painting, deck repairs and additional electrical work. The reasons we keep hiring Munoz Construction is because they do excellent work and Jose Munoz communicates very well throughout the project so there are no misunderstandings and the customer gets exactly what they want. Jose’s teams are always respectful of our home, making sure to cover the floor with drop cloths and cleaning up thoroughly before leaving each day. Jose is meticulous about everything being done properly to achieve the best possible result. We couldn’t recommend Munoz Construction more highly. This is the only general contractor we will use as we trust them implicitly."

"All Renovations was hired to add a carport and a new sunroom addition to our home. They were priced reasonably, worked closely with us on all of the permitting and planning needs, assisted with multiple decisions that normally come up on a large project such as this, and were polite, friendly and very easy to work with. Overall, we are extremely happy with the finished project and we would recommend them to anyone."

"Edwin, one of the owners of this company worked closely with me and kept me well informed about what was going on. He was polite and efficient. His work crew did a beautiful job and I plan to hire them again in the future and you should, too!"

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.
