Great customer service and amazing end product. They worked on renovating the outside of my house and it exceeded my expectations. I highly recommended them!

Alex did the waterproofing work for our two decks. The work looks excellent and the care he took in installing the system and flashing should ensure a good functioning system for years to come. He coordinated very well with other contractors on the project and is very professional and pleasant to work with. I recommend him greatly.

Alex was easy to work with on our deck project. We looked into many options for a waterproof deck at our lake cabin. We had to replace a cracking and leaking tile deck and Alex's product was a good solution. He was flexible in working with our contractor and was always prompt in answering our calls or texts. He showed up and did the work when he said he would - which doesn't always happen in the building industry! I would definitely recommend AG Waterproofing and Alex Gutierrez for your deck project.

Alex and his team did an excellent job for us on 2 homes in Chelan this last year. We'll hire him again soon!

Alex was the only one that could save our botched job on a new build. He was incredible to communicate with and he took his time going over the whole process while he was swamped with scheduled jobs. Alex went above and beyond!

Service questions
1. Should I stay home during roof replacement?

It's not necessary to stay home during roof replacement. Roofing work is noisy and can cause vibrations inside the house, which might be uncomfortable. Most homeowners choose to leave during major parts of the project, but our team ensures safety and keeps you updated, whether you're home or not.

+-

The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.

3. How to hire a roofing contractor?
+-

To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.

4. How to check if a roofing company is legit?
+-

Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.

5. How to choose a roofing company?
+-

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.

6. How do you know if your roofing contractor is ripping you off?
+-

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
