Recent Testimonials

Hello Jacky and team Just a short note to say ‘thank you’ for our new conservatory. We are delighted with the finished building and appreciate the trouble that you went to get everything absolutely right. All your workmen, particularly Darren and Josh, were very efficient and were a pleasure to have around (as long as gallons of tea were provided!).

Written Testimonial

Dear Cousins Just wanted to say thank you for the lovely bouquet of flowers you sent us on completion of our lovely conservatory. We are just laying a new wooden floor in there and look forward to using it over Christmas and the New Year. Please pass on to all staff concerned, our wishes for a very Happy Christmas and a Happy New Year.

Angel and Martin Russell-Croucher

Written Testimonial

A very good experience from first visit to show through to completion. Excellent attention to detail by Gavin, Jackie and Roger during quotation and specification. Similarly during installation by the two Daves work was carried out efficiently again with good attention to detail and finish. Cousins have transformed an old shabby conservatory into a bright modern living space.

Review from Google

Dear Cousins Having just received your guarantee document in relation to our new conservatory we’d like to say that we are very pleased with it. It has exceeded our expectations. The construction is excellent, the finish really good. We’d particularly like to commend your teams, Ian and Louis, LJ and his crew for their excellent work. It’s (almost) been a pleasure having them here, despite them drinking us out of tea and coffee and elder-flower cordial. So many thanks to you all for a job very well done.

Written Testimonial

Dear Sean and Sam Cousins did an excellent job on our new Summerhouse. The building size had to be adjusted for planning reasons due to the proximity of the boundary and this they managed very well. The groundworks were completed very well and with minimal mess.Finally the fitting team arrived the following week and meticulously put together the building with particular attention paid to the cedar shingle roof. They also painted any scuff marks that had occurred during the build at the end of the job. All in all an excellent building and well put together and at a competitive price. We would throughly recommend Cousins to anyone looking for a garden building or similar. Ours certainly looks beautiful.

Written Testimonial

Dear Sean We are delighted with the Summerhouse that you have supplied for us, very well made and constructed. The organisation at your end has been perfect and the people that you sent to do the work were really efficient and good humoured, a pleasure to meet. Your team had to carry all the items a considerable distance. The laying of the concrete base and construction of the building went so smoothly that at one point I began to wonder if I was dreaming.

Written Testimonial

We've always been impressed with our Cousins conservatory. We've had it for 11 years and it's the room we spend the most time in all year round. We've just had the roof upgraded to an ultra frame roofing system, ordered through and fitted by Cousins. The workmanship is great, the roof is fantastic: much better light levels, improved thermal performance (keeps the space cooler on sunny days and warmer in the colder evenings), looks great and is so much quieter than polycarbonate when it rains. We'd recommend Cousins, their products and their fitters very highly indeed.
