Trustindex verifies that the original source of the review is Google. Absolutely top-class service from start to finish. John and the team were professional, efficient, and clearly experts at what they do. From the first inspection to the final clean-up, everything was handled with care and attention to detail. We noticed a huge difference in warmth and energy efficiency almost immediately after the insulation was installed. Communication was clear throughout, and the work was completed on time and within budget. I wouldn’t hesitate to recommend them to anyone looking to improve their home. A fantastic experience all around!Trustindex verifies that the original source of the review is Google. We’re thrilled with the work done by Complete Insulations in Dublin! They expertly insulated our attic, we got exterior walls wrapped with insulation blocks and had the beads pumped into the bricks at the front of our home. The exterior render they applied looks fantastic and matches our home perfectly. They did everything to make our home warm for the winter months. We now have a B3 rating. We have all new triple glazed windows so we hope to see a huge improvement on our bills this winter. Thanks guys ☘️Trustindex verifies that the original source of the review is Google. Complete Insulation did the external walls and attic insulation in our house. From start to finish everyone we dealt with was extremely professional. The majority of the work was done over a 2 week period. The house is a 1930’s bungalow, so was in need of modernisation.the difference made is huge. I can’t highly recommend enough the work that was done and would strongly recommend their services.Trustindex verifies that the original source of the review is Google.

I refer my friends to themTrustindex verifies that the original source of the review is Google. We got the keys to our E1 energy rated red brick home, built in 1910, on the October Bank holiday weekend. We had a baby coming in January and so wanted to make the home more comfortable in a very short timeframe. Tom came to our house in November and advised on the best approach to insulating and modifying the house with our budget and ambitious timeframe. Tom mobilised a great team immediately who insulated all the walls and ceilings, replaced the windows and doors, rewired the entire home (something we hadn’t originally planned but needed to be done urgently) and upgraded the heating system. The special features in the house like coving and skirting were reinstated to match exactly the original print. Tom linked us up with great tradespeople when we found an old chimney breast and decided to install a beautiful stove which is now one of the best features in the house. Tom project managed and kept the project moving when our baby arrived unexpectedly early and we were unavailable to make key decisions which could have delayed the completion of the project. Complete Insulations applied for the SEAI grant on our behalf and coordinated with a BER assessor to complete an assessment. We moved back into our lovely warm B2 energy rated home with our new arrival in January and couldn’t be happier. I couldn’t recommend Tom and his team enough.Trustindex verifies that the original source of the review is Google. Complete Insulations insulated the front and back of my house 4 years ago and the finish still looks like new. They also insulated my attic and all the work has made a great difference to the warmth in my home. The workmen were great and cleaned up every day before they left. Complete Insulations applied for the SEAI grant on my behalf which saved me the paperwork and everything was so efficient. They made sure the finish was the same as the original facades so that my house didn’t stick out like a sore thumb, which other companies I had received quotes from wouldn’t do. Would definitely recommend them!Trustindex verifies that the original source of the review is Google. The Complete Insulations team recently topped up our attic insulation and put insulation above the bay window and kitchen extension. I can't believe how fast they were, done in less than a day! Apart from emptying the attic, there was nothing we had to do ourselves, they took care of everything else and even used the hoover to clean up after themselves. Really lovely friendly guys and very efficient. All our dealings with the office were very straight forward and easy, the whole thing couldn't have been easier from start to finish.Showing only 4-5 star reviews
