    "We had been looking for a pro to finish the basement for a few years. The previous company we had tried to work with had fluctuating pricing and very difficult email correspondences (time wise) in addition to putting us off for 6 months. I gave up trying. I looked on Home advisor for a pro and found Living Stones. Adam was prompt returning my initial email, set an appointment to look at the job, very quickly gave an estimate and was ready to get to work the following week. The framing and drywall was completed in 3 day! I highly recommend Living Stones Construction Management."

    "Look no further for your home improvement needs, because Basement and Decks R Us is the pinnacle of excellence! From the moment we reached out for a quote to where our basement stands now, Martin and his crew have been nothing short of phenomenal. First and foremost, scheduling with them has been a breeze. They respect your time and theirs, showing up promptly and when promised. Itâ s a rarity to find such punctuality in the construction industry, and Basement and Decks R Us delivers on this front flawlessly. Quality is at the core of everything they do. Despite the ongoing work in our basement, there hasnâ t been a single disruption to our household. Their attention to detail and craftsmanship is evident in every aspect of the project, from framing to painting. Speaking of painting, Martinâ s keen eye for design saved us from a potential disaster. While we were set on a particular color scheme, he gently suggested that it might not yield the results we envisioned. Though we persisted, he graciously accommodated our wishes. However, when the final paint went up, Martinâ s foresight proved invaluable. Without hesitation, he rectified the situation, ensuring our satisfaction every step of the way. What truly sets Basement and Decks R Us apart is their unwavering dedication to customer satisfaction. Martin has been a constant presence, walking us through the process and discussing next steps. His attentiveness and willingness to go the extra mile have made this journey stress-free and enjoyable. In conclusion, if youâ re considering any home improvement project, big or small, look no further than Basement and Decks R Us. Their unparalleled combination of affordability, quality, and customer service makes them an absolute blessing. Thank you, Martin, and the entire team, for turning our house into a home weâ re proud of!"

    "We needed a new sliding glass door. The old one let in both the cold and the heat and unfortunately it didn't lock all of the time. After researching several companies, we contacted Champion Windows of Denver. They sent Joe B. and Joe C. to our house to tell us about their products. Both men were extremely professional and knowledgeable. After a few short weeks, our new sliding glass door was ready to be installed. The installation crew was professional, polite, and experienced. The installation was completed in less than two hours! We are very happy with our new Champion Windows sliding glass door. Got Windows? Then you MUST call Champion Window! You'll be totally pleased with their products."

    "Alignment Construction was hired to remodel/renovate my Master Bedroom, Bath, and Guest Bath. The rooms were original, 1991. Vance and crew removed all exposed lighting and replaced with recessed. Hardwood flooring was installed in the bedroom and the Master Bath gutted. They removed an existing small shower and, with innovative design, were able to build a large shower with bench seating. This was complicated by an existing window wall that I wanted to keep. By utilizing every inch of space available, they were able to install a stackable washer/dryer and hide it behind a door, giving my home two laundry stations. Vance built a custom vertical sliding storage unit that sits alongside the washer/dryer. I had a good idea of the look I wanted and once conveyed to Vance, he was instrumental in the selection of fixtures and finishes. Everything was 100% professionally handled. There is a contract with cost clearly stated and most importantly, zero surprises. He and his team arrived punctually every morning and the job was completed within the time frame allotted. I live in a strict HOA governed community and Vance adhered to every restriction. My neighbors commented he was there every day - which is evidently unusual for many General Contractors. I will hire Alignment Construction for future work and recommend him without hesitation."

    "Our home needed most of the wood-based trim to be replaced, and both the home and the standalone 4 car garage needed paint. Candace was a pleasure working with during the contracting and execution of the project, and helped us select a color that we are very happy with. Gio replaced all of the home trim with Hardiboard. I was very pleased with Gio's confidence and ability to manage the trim replacement around our second story deck. His team removed gutters in order to replace the trim. Then, they painted the gutters and reinstalled them. I was also pleased with Gio's experience using the Sherwin Williams Emerald Rain Refresh paint. We love the results, and no longer need to worry about exterior water damage."

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.
