Two Replacement Windows
Had 2 windows replaced due to previous windows causing damp issues. The team were very polite and incredibly knowledgeable. I can't believe the difference with the new windows. The quality is amazing. Will definitely be using the company again to replace more windows and have already recommended to family and friends.

New Cottage Windows
Had some windows fitted in my air bnb cottage. The guys did a great job. I had the old style with the wood dividing the panes of glass and they look amazing so in keeping with the cottage style. Everything was left spotless. Would highly recommend Optimus and will definitely be using them again. Thanks Optimus

Highly Recommend this company
Highly recommend this company, for the initial quote Chris turned up on time, talked us through all options, and some we had not even thought of, very knowledgeable with no hard sell. The fitters Tim and John turned up at 8.30 everyday, worked hard and we are so pleased with their fitting and the end product Many thanks to you all

Faultless from Start to Finish.
What a great experience. From beginning to end our dealings with Optimus have been a delight. Nothing was too much trouble for them. From the original and ongoing messages with Chris, the survey with Tim, and the fitting with Jon and Tim (with a guest appearance from Chris!) everything was a pleasure.

I love my new door and window!
Great and very stress-free experience with Optimus. I love my new door and window. The door fitting was delayed due to the door not passing the quality check initially but a new date was quickly arranged. I felt comfortable having Jon and Tim at the house and they just got on with the work without any issues. Would certainly recommend.

Very professional
Dealt with Chris the owner who was helpful from start to finish. Didn't push the sale & nothing was too difficult. Fitters were also very professional & the workmanship was second to none. Great experience & glad I opted for a local business in Oreston. Recommended.
