Marcin and the THI team have been tremendous when designing and fitting my windows. Always available at the other end of the phone, able to provide frank advice and design effective solutions to issues as they emerge, I've been continually impressed with their professionalism.

Not only that, but their tradesmen are sensible, honest and complete their work to a properly high standard, whilst being a good laugh.

I have no issues recommending THI. The service I received was excellent from beginning to end, and they were more affordable and much more professional to deal with compared to their competitors.

All in all, top notch customer service and sound, flexible tradesmen, both of which mean that the quality delivered is on point.
