Totally professional & reliable customer service
I knew I wanted replacement doors and windows but had no idea of the products available. GHI patiently talked me though everything, suggestive styles and colours appropriate to my home. The advice I was given was spot on. The installers were really professional and meticulous in their work and did a brilliant job. Thankfully somebody recommended GHI to me, I’ll do the same for someone else!
