Service Pros


    "This was our second major project with Primework Construction and we couldnâ t be happier. It was so easy for us, Ben and his team handle everything. They took care of the architect plans, the engineering, permits, facilities for the crew, and clean up. They worked within our budget and completed the project ahead of schedule. They really go out of their way to treat us well. We highly recommend using them for any of your projects, big and small."

    "Town is a busy restaurant so our walls get dirty very fast. John and his crew did an amazing painting job making sure the restaurant looked top notch again. These guys came in the middle of the night and got it done very fast! They’re very efficient and detail oriented which is just what we needed! We’ll definitely be using them again! Thanks guys!"

    "Living in San Jose, we decided to team up with Eddie from Barak Builders for a complete overhaul of our kitchen and living room. I have to say, we are beyond pleased with the results. Their work has been outstanding, and we could not be happier with the transformation. The way they brought our vision to life was truly impressive. We are so satisfied with their craftsmanship that we were already thinking of hiring them again for a master bath remodel soon. Barak Builders has proven to be a trustworthy and reasonably priced company, and we have complete confidence in their services."

    "Our work that was completed by Pure home remodeling was of the highest quality. Adi and his team worked very neat, carefully and with extra care to finish our lovely remodeling to our home. Adi’s vision into the understanding, planning and design the spaces was very useful and helpful. He was available to us during the whole project and he answered all the questions we had (before and during the work) and always gave us recommendations. At our house, they remodeled the master bathroom, relocated the closet at the master bedroom in order to make the bathroom much larger. Each and every part of the master bathroom was finished perfectly. Due to some issues and difficulties of the remodeling, they had to move the plumbing and HVAC ducts so it will allow them to take down the separation wall between the kitchen and family room. This entire work was finished way above our expectations. Everything was started and finished less than the timeframe Adi had given us. The total price for the work was also within the range of the estimate and we had no hidden charges at all. We would highly recommend Pure home remodeling."

    "After flood damage and an unresponsive contracting business, I was so lucky to be referred to Ali and Envirobuilt through Angi. I am a teacher and needed to minimize missed days and Ali was incredibly responsive to my timing needs. He went above and beyond searching for wood to match the floors in the house and even went to Redding to get the wood for my timeline. If I am being honest, I have not had a lot of luck with contractors before. They would push me off and try to nickel and dime me for everything. Ali was motivated to finish the job quickly and to my specifications. The job was even finished early so I could get back to my students. The dry wall was textured perfectly to match the rest of the wall and the paint was matched exactly even though we did not have the old paint. The floor looks beautiful and with great work on the floorboards. I have never had such a great experience with a contractor. I give my strongest recommendation to Ali and Envirobuilt for your projects."

    "I heartily recommend Ignacio and Martinâ s Bay Area Construction to anyone doing new construction or remodeling. I hope to hire him for a future project. Ignacio Martin was our general contractor for a complete home remodel (see below.) He was a great partner in the project, suggesting our interior designer, structural engineer, and floor refinishers. I could put my full trust in Ignacio, his subcontractors were reliable, timely and did quality work, he was always budget conscious and saved us money by keeping the project on schedule, coordinating building permits and inspections. He shared good suggestions. For example, I wanted to patch the existing floor which would have looked cheap. At his suggestion, for a little more money we re-finished the floor which looked fantastic! His idea we re-use interior doors and jambs also saved $ thousands and looked great. Home Remodel Project Scope: Full electrical upgrade (including main service panel), removing two load bearing walls, fully gutting and expanding the kitchen, both bathrooms and laundry room, removing wallpaper, floating, and repainting all rooms, insulating western walls, re-finishing floors, reconstructing two walkways and installing 40â of French drain."

    "I wanted to express our appreciation for the excellent service we got with HQC.

They helped us with everything from design, permits and all throughout the construction. Weâ re almost done and could not be happier!"

Unexpected incidents never phased him; he was flexible and adjusted plans accordingly, never charging us more for all the extra work needed to repair unforeseen problems. The final project cost was very reasonable considering the high quality of workmanship we received. We will recommend Yonis and K & B Remodeling to our friends."

    "From the first moment that I contacted Gil with W And W Builders Group. to the last moment (being the final job inspection,) I could not have chosen a better company to design and build my master bedroom and dual baths addition/remodel. Mr. Gil Perez, along with his interior design expert, Magen , worked out a floor plan that not only would accomplish my goals and meet my particular needs but would also be within my budget. Magen worked tirelessly with me to complete the interior design aspects and helped me throughout that phase to develop a project plan that reflected my style; her expert guidance was invaluable! The project manager, Adam, oversaw every aspect of the project from start to finish with a diligent demand that the job be done to my satisfaction. He demonstrated terrific leadership qualities; his straightforward, competent ability to manage the project soon gained my trust and I was never disappointed with the results. He consistently maintained a confident while respectful supervision over his team and I would very often depend on his expertise whenever I had a decision to make about the project. The crew were all terrific and my project could not have been built by a better team of individuals each dedicated to their particular job. Without exception, everyone involved was professional, courteous and always mindful of my living space. The end result is an amazing, 100% completed project that also remained with the budget; I could not be any happier with the outcome of doing business with W And W Builders Group Inc..!!!"

Frequently asked questions

  • It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
  • You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
  • It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.

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:

  • Have you completed a job like this before?
  • Do you have a list of references I can contact?
  • When are you able to start the job?

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. 

  • How many years of experience do you have?
  • What’s your permanent business address?
  • Are you licensed to work in my area?
  • When did you earn your business license?
  • How do you handle warranty service complaints?
  • Do you have worker’s compensation, property damage and personal liability insurance?

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.
