What people say about building with us

"We hired Keystone to convert our attic space and turn it into a bonus/game room. He was extremely professional throughout the process and communicated well. He is very meticulous and does amazing work!"

-SF

Attic Conversion Client

"We had a great experience with Keystone Structure and our contractor, Martin. We had a leak in our bathroom and he responded promptly and came over quickly to fix it. Not only did he stop the leak, but he also did an amazing job remodeling our bathroom. He prepared the estimate and worked with our insurance company. Martin is reliable and his work is beautiful. I highly recommend him for any home improvement project."

-NK

Water Damage Repair and Bathroom Remodel Client

"After personally trying to purchase materials, there were problems with delivery and installers installers told me they were afraid they would damage my home and the other area. Martin at Keystone was recommended to us, came to look that day, agreed to install, had materials onsite within the week and work completed above my hopes. Months later, he also advised me on flooring remodeling, and did a light bathroom remodel for me. The Best!"

-CI

Master Closet Remodel Client

Thank you, Martin Isaac and his company Keystone Structure, for a job well done! After my Tesla alerted me to an overheating outlet, Martin responded immediately and discovered faulty wiring and damaged components that could have led to a house fire. He quickly made the repairs and ensured everything was safely installed. Professional, knowledgeable, and responsive—I highly recommend them for any electrical work!"

When it comes to SEO, there isn't a magic formula to instantly send your site off to the #1 search result on Google. But there are some basic principles you should follow for a wonderful starting point. Here are the top 5 SEO practices to start with: #1 Write for people, not for search engines Always write original, interesting, high quality site content that's error free and relevant to your site. Search engines like Google can easily detect content that is duplicated from elsewhere online, that contains grammatical errors, or that is stuffed with keywords. #2 Add a blog to your site and use rich media To engage your site visitors and blog readers, create posts that include non-textual media like photos, videos, or original visualizations (infographics). Having that extra content (especially if it's captivating) will increase the time users spend on your site as well as the likelihood they will share your site with their own community. #3 Offer a positive user experience throughout your site Google will know if you're using your site to aggressively advertise your service, or if you're being too pushy. Always aim to offer site visitors a pleasant experience on your site. That means clear content, support when needed, and always an option to go back. #4 Create a network of internal links (but don't overdo it) Add links between different pages of your site and your blog, but try to follow a process that feels organic rather than heavy linking meant just for search engine crawlers. Link between pages that make sense, for example, on your services page, link a certain industry specific term, and link it to a blog post you wrote about it, that gives more information on that term. #5 Always check your site's Core Web Vitals Core Web Vitals are a standard site performance standard initially created by Google. The report shows site owners how their site pages perform 'for real,' how long it takes for site visitors to load site pages, and it offers ways to fix issues, if there are any.
