"GS Exterior Experts is a highly professional organization and did a superb job on the re-siding of our home. From the first contact with Ernest to the final walk through with Oswald, everything was top-notch! Upon initial contact with Ernest, he took the time to cover all the details and describe exactly what the crew would be doing and gave initial quotes for various options, sticking to the exact cost of the option we chose, which was to completely cover our house and detached garage. I should point out here that their quote was less than others. The crew (headed by Omar) showed up exactly on time each day and stayed as late as necessary to complete each day’s task. The entire hard working crew was pleasant, positive, respectful and worked together incredibly well throughout the entire project, finishing on schedule despite having to do some extra work and adjustments to the original plan. They really seemed to enjoy what they were doing each day, despite the cold temperatures (late December at an elevation of 8,000 ft). The attention to detail was the best I’ve ever seen in watching over 30 years of construction improvements by various crews on our house. (And that’s saying a lot as we have had really good luck with some fantastic construction crews over the years.) It really was amazing to watch how efficient and brilliant the crew was in making sure everything was done to perfection! They were true artists in their work. Any requests I had for specific details during the install were done exactly as asked with a smile. The same is true of any questions I had throughout the entire process. One of the crew members (Moses) was extremely helpful in fulfilling any requests and answering my questions and checking with me to make sure I was happy with specific results. I just cannot emphasize enough how well the work was done- the meticulous attention to detail was outstanding! Following completion (which was the evening before Christmas eve), the project manager Oswald took the time to do a final walk through with me a few days later, immediately taking care of the few tiny concerns I had. He, like the rest of the crew he manages, was amazing- so professional and pleasant to work with! I would highly recommend using this company for any project involving services they offer. They definitely go above and beyond expectations."

"This company doesn't do interior home jobs, yet they helped me with no hesitation. There are no words that can express how wonderful this company is. Rex Roofing & Restoration LLC; is very professional, and went over and beyond to help with the horrible situation that I was in. I was without hot water for over 3 weeks from water damage of a hot water heater. I could not get Teir1 Restoration in Castle Rock CO to move forward after the mediation was done. I contact Joe, and he took the time to listen to my issues and offered to help me out. His Office manager Shannon even got a temporary floor set for the hot water heater within two days of contacting me. After a little over 4 weeks I finally had hot water, and it was so apricated. Shannon got the drywall done in less than a week, then got me on the schedule for my hard wood floor installation asap too. Once my project was completed, that was when I found out that this company primarily does Hail damage on homes in Colorado. It almost brought me to tears, how do you thank a company stepping up like that. THANK YOU so much every one of you at Rex Roofing & Restoration for all your help!"

"I couldn’t be happier! From the time Gary came to do my roof inspection to the final paperwork, everything went to smoothly. Gary gave me such honest advice and feedback. When the crew showed up to replace the roof, they were on time and worked so hard. Finished in the same day, including cleanup. Gutters were installed the next afternoon. It’s now two months later and all my neighbors are either still waiting for materials or have many issues with their installs. So glad I went with JR Roofing and avoided all those headaches. I hope I won’t be needing another roof anytime soon, but if I do, I will be using JR Roofing again without question. So happy!"

The average cost to hire a handyman ranges from about $40 to $140 per hour. Average project cost ranges between $180 and $700, but the cost per hour and per project depends heavily on the type, size, and complexity of the project. The pro’s experience level and your location also factor into how much a handyman charges per hour or per project. You can also expect to pay higher rates or additional fees for emergency services, or around periods of high customer demand, like holidays.
Gutter installation costs from $4 to $30 per linear foot. Cost factors include linear footage, type of gutter, and material (aluminum, copper, etc.). The number and length of downspouts also impact the cost. Roof repairs are another potential cost. Optional add-ons include gutter guards or gutter screens to keep debris out of the gutters.
Yes, most states require roofers to be licensed, and for good reason. Hiring an unlicensed roofer could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost to replace siding for your home is $11,450 on average. But siding replacement can cost up to $40,000 or more, with the largest expense being your chosen material. For example, for a 2,000 square feet house, the average cost of siding materials such as vinyl is between $9,000 and $14,000. Wood siding is a little more expensive, ranging from $16,000 to $26,000. However, for the same size house using brick or stone, that cost jumps to $18,000 to $100,000. When choosing to replace your home’s siding, it’s essential to consider your climate and longevity.
Gutter cleaning costs about $170 on average, ranging from about $75 to $400. Cost factors include the type, length, and height of your gutters. A multiple-story home with gutters high off the ground and accessible only by ladder or working on a steep roof will cost more than a single-story house with a relatively flat roof.
