West Standard is a great siding company and I enjoyed working with Max and his team. Would highly recommend them for any projects you’re looking to do.

We used West Standard to install Hardie plank shingle siding on our house along with a new front door and 5 windows. They were great to work with. They gave us a very reasonable bid and were readily available. They were courteous and went above and beyond, even doing extras like taking down and hauling away an old rooftop antenna since they were going to the dump anyway. They are eager to please and do careful work. Serge was a great foreman and Yaro was very responsive and nice. Max came back to finish up and was great as well. We recommend them without reservation!

West Standard Construction did an excellent job installing the James Hardie siding on my house. The workers were very professional and hardworking.

West Standard is awesome!!! They quoted a fair price and started work immediately! They replaced all the siding and windows in a fairly large (700 sq. ft.) ADU and replaced the roof and rain gutters as well. They finished in a short time and we are very happy with what they did. Their sales manager Yaro was very pleasant to work with AND the company did everything Yaro said they would do. We are now able to obtain fire insurance at a reasonable price. This company is the BEST!!! Bruce & Christine Johnsonbaugh

I recently hired West Standard Construction for siding, window, and roof replacement, and I'm thrilled with the results. Their workmanship is exceptional, and they provided excellent service and communication throughout the process. Highly recommended for anyone seeking quality home renovations.

West Standard Construction truly impressed me with their siding replacement service! Initially, I was leaning towards wooden siding, but after their expert recommendation, I opted for fiber cement—and I'm so glad I did. Their guidance made the decision easy, and the results speak for themselves. Highly recommend their services!

They were very fast! Our roof was leaking and they fixed it in-between storms. Great job. Cleaned up afterwards. I recommend them.
