Client Reviews
Don't just take our word for it. Here's what our customers have to say about Scotmax Home Improvements.
“Just had our soffits and gutters replaced by Scotmax. First class service from start to finish. Father and son, Gary, were excellent and really professional.”
“Had my soffit and facia replaced today, can't recommend this company enough, friendly reliable and very helpful with any queries. Guys turned up on time and done an excellent job despite awful weather. Delighted with the outcome. Would defo recommend this company and I will use them again in future. Thanks so much!”
“Scott and Chris have always looked after us and they offered us a great deal to get 2 doors replaced. Due to COVID, installation took longer than expected but they kept us informed. John, who did the install, worked like a Trojan to get the work done and didn't even take a break! Really happy and will be back for further home improvements.”
“Spoke to Chris at Scotmax during lockdown and he quoted me for windows. Just got them fitted the other day and they look great. Great service, friendly, excellent communication.”
“From the original quotation to the fitting of our new windows and doors we cannot recommend Scotmax more. The fitters did a great job and left no mess and even there after sales has been second to none.”
