Verified Speedy execution of a good job! Prompt arrival and speedy completion of job by personable staff. Left the house cleaner than it was when they arrived! Unpleasant environment to work in, transformed into a roof-space which is now clean and better insulated, with the sealed insulating mat attached to the rafters. George Simon – May 20, 2026

Verified A hard job very well accomplished … The guys working were very respectful and every day left the house very clean. A horrible job but they worked long and hard. Never complained. There was a lot of mess which they loaded in their van every day and disposed of. I would highly recommend this team to work in your home. Isabel Holmes – May 5, 2026

Verified A professional job by any standard. The team (led by Jack) turned up on time and because I missed the call from them telling me they were on the way they sent a text message. I was expecting a 2 day job because I had spray insulation done previously (by another firm) which had blocked the air vents. They were polite and talked me through what they were doing step by step. On completion everywhere was left as if they had never been, Brilliant! I’d recommend them any time. Jeff Adams – April 27, 2026

Verified This company were superb. This company were superb. The rep offering the work was taking what we needed into consideration and offered good advice. The workers were quick, clean , very respectful. The top of the house is so quiet now it’s unbelievable. We live on a main dual carriageway and there is no sound at night at all. Also the top of the house is so much warmer. After living here for 50 years I’m amazed at what could have been achieved years ago, we did have insulation but not to this quality, this is superb and works. Bernadette Thomas – April 15, 2026

Verified They removed the spay foam quickly and cleanly I used costal prime to remove spray foam from my loft. They gave me a cost price which was a lot cheaper than other quotes I received, which they kept too. They removed the spay foam quickly and cleanly. I also received a follow on phone call making sure everything was okay and was there any problems with the removal of the spay foam. I would highly recommend Costal Prime in the removal of spray foam from loft spaces. Thanks David Harris – June 18, 2026

Verified Absolutely amazing! I wanted to share a really positive experience with Coastal Prime. My mother recently had a survey arranged, and Nick the surveyor came out to assess her property. What stood out immediately was his honesty and professionalism. After carrying out a thorough inspection, he explained clearly that she didn’t actually need any new insulation. In a time where it’s easy to feel like companies might push unnecessary work, it was genuinely refreshing to see the opposite. Nick took the time to reassure her and answer all her questions without any pressure or sales tactics. It’s great to see a company like Coastal Prime operating with this level of integrity. It really builds trust and shows they care more about doing the right thing than just making a sale. Highly appreciated and strongly recommended. Ethan dolan – March 22, 2026

Verified Trustworthy and customer freindly. The action required was very quickly organised. The office staff were polite and knowledgeable and the people I actually met were very efficient and a delight to meet. There were one or two problems which were solved and didn’t phase them at all. The whole experience was quite painless. I would happily recommend this company. Hilary – April 22, 2026

Verified Very impressed with the work ethic of the contractor Contractor arrived on time, very pleasant and friendly. Got “suited up” and straight on with the job and kept at it until completed. Very impressed with the work ethic of the contractor, his dedication to the task and the fact he bought in a vacuum and cleaned up after job complete. Andrew Emmerson – July 8, 2026

Verified Professionalism and Expertise Michael and his team arrived on time, introduced themselves and were kind, courteous and chatty throughout, frequently asking me to see and discuss their work. They completed the task in 4 hours and did an excellent job in tidying up. Overall, their work and professionalism exceeded my expectation. Highly recommended. Charles Doig – July 16, 2026

Verified A thorough job The team that carried out the installation were prompt, and despite the heat – especially in the loft – they cheerfully got on with the job. They cleared up afterwards and left everything tidy. All in all, a really nice experience. This also applies to Duncan. Eric Holland – July 11, 2026

Verified We would unreservedly recommend the company Coastal Prime removed loft insulation in our house’s roof. The team arrived early and worked tirelessly during the day – starting at 8am and finishing at 7pm. The team were courteous and friendly. They made sure that they worked cleanly and carefully and at the end of the day cleaned up after themselves. They were very respectful of our possessions. We would unreservedly recommend the company. David Luyt – July 22, 2026

Verified I had my spray foam removed by Coastal prime I had my spray foam removed in July by Coastal prime. The team were very polite and extremely tidy didn’t need to ask them to clear anything away. Catherine Reardon – August 1, 2026

Verified I am very pleased with the work! The team that arrived were very polite and professional. They worked very hard in the heat and tidied up very well. They explained everything to me and I am very pleased with these work! Ann H – July 21, 2026

Verified Coastal Prime were outstanding! Coastal Prime were outstanding – a genuinely excellent company to work with. Their staff were helpful, friendly, and consistently went above and beyond for us. The installation team were a great group of guys: polite, quiet throughout the foam‑removal process, and they left our home immaculate after what is normally a very messy job. Greg – July 15, 2026

Verified Competitive Price & Totally Trustworthy Competitive price. Professional. All work completed to the highest of standards. Every member of the team is excellent. I could not be happier with the work carries out Ian King – July 21, 2026

Verified Polite & Efficient The team came on time and were polite and efficient throughout. They cleaned up after themselves at the end of the day after doing a grand job. Jane Hurdle – July 30, 2026

Verified A very good investment It was very good investment as we will save on heating costs for the house. Our previous fibreglass between the ceiling joists was causing damp in the rafters which Coastal Prime has now treated. This treatment will also make it easier to sell when we downsize. John B – July 19, 2026

Verified TOP JOB FROM COASTAL PRIME From the first contact to an inspection From the first contact to an inspection of our loft insulation, then the actual work replacing this our experience with Coastal Prime Ltd was nothing short of exceptional. The whole process was explained in detail and made fully understandable. The guys completing the new insulation worked together to achieve a top job with no mess what so ever. Would highly recommend this company. John Monaghan – April 25, 2026

Verified Excellent loft insulation Excellent loft insulation. From start to finish, the staff were professional, kind, and polite to my elderly parents. A total credit to the company. Liz Williams – July 18, 2026

Verified I was impressed by the honesty I was impressed by the honesty and professionalism of the surveyor Duncan Fraser and he gave me a true outlook of the company and the product. I assessed his information and it enabled me to make a decision to go with the company product without hesitation. The crew arrived to install the product and they were courteous and polite completing the work efficiently and without any problems. Well done Lydna – June 10, 2026
