Peter done an amazing job on our double storey extension - he finished the work to an exceptionally high standard and within the timescale. He even helped us save money on our kitchen telling me where to go and buy it from. I still have some more work to be completed on my house later in the year so I will be getting Peter back round to complete this work. Thanks for the great work Peter! - Jonathan Wall

Wouldn’t hesitate to recommend Peter to anyone, fast response, great ideas, great work, kept to budget and took care of everything. Lovely 30sqm extension delivered within 3 months, from the foundations to the roofing. The whole team, both employees and subcontractors, were helpful, professional and delivered everything to a high standard. - Marianne

Excellent company and fabulous end result with no hassle along the way. I cannot recommend them highly enough. They were polite, friendly workmen who did a professional job with minimum mess and fuss and we are extremely pleased with our new loft rooms. When we went to see some other conversions, they had done locally and heard the good feedback from those customers it was really a no brainer to go with Belmondo. Many thanks Peter. - Gerard B
