We were looking to replace our solarium with with proper extension and found 4K on 4K ( Teo and Steve) came to give onsite estimates in price and schedule. They were very friendly and listened to our needs. Once everything was agreed work started. Everything was as scheduled and promised. They were very professional. The work site was cleaned before they leave everyday. They were very accommodating and efficient and met our expectations. We were so pleased with their work, we had them renovate our custom kitchen once they finished with the extension. We are glad to have found 4K and would recommend them to our friends. Thank you Teo and Steve.Read More
