I strongly recommend Innovate Insulation for any homeowner looking to insulate their attic with Spray foam. From start to finish, the team was extremely professional, provided a competitive quote, and offered a flexible approach to installation.
Andrew and his crew installed spary foam in our attic over the weekend and did a outstanding job. They kept our home spotless throughout the process, which are truly appreciated.
We are satisfied with their work- our home already feels warmer and we have started using less heating since the attic insulation was completed.
If you're considering spary foam insulation, Innovate Insulation is the company to trust.

I had a fantastic experience with Innovate. From start to finish, the whole process was smooth and professional. They were knowledgeable and helped me select the perfect insulation. The installation was quick, clean, and the results are amazing so far as I have already noticed the temperature difference in my home. I highly recommend them!

Fantastic . What I thought was going to be an awful job of re-insulating an attic in an old house full of stuff , Kyle and the team got in there and did the job in no time . Everything was done and dusted that day . We are now really beginning to see the benefits of having the attic insulated . The heating is now switched off much earlier . Thanks so much everyone - I would highly recommend Innovate Insulation - a superb job done . Thanks guys !

We were looking for a reliable company to do spray foam insulation in our attic, and we’re so glad we found Innovate Insulation. We first met them at the RDS Ideal Home Show, and right away we knew they were the right team for the job.
The insulation was completed just yesterday, and the results are already amazing. A huge shout out to Josh and the entire team — from start to finish they were fantastic. They answered all of my questions, were always happy to pick up the phone for even the smallest things, and were extremely professional throughout the whole process.
I couldn’t recommend Innovate Insulation enough!

This week I got my Loft insulated with Innovate Insulation. From my first contact with Mal and then Josh, the experience was totally professional. They listened to my requirements and concerns and quickly assured me that everything was straightforward and nothing was too difficult. They gave a a date for Insulation and the Team arrived early, they were very friendly and efficient. They left the house immaculate... I would have no hesitation in recommending this Company and have already passed on their details to a couple of my neighbours....

I had a fantastic experience with the team at Innovate from start to finish. From the moment I received the initial quote to the final installation, everything was smooth and professional. Josh was incredibly knowledgeable, addressing all of my questions while also educating me on the many benefits of spray foam insulation. I live in a 1960s home, and I’m already noticing a difference. The team was also incredibly neat, leaving the house spotless throughout the entire process. I highly recommend Innovate for anyone looking to improve their home's insulation!

We recently had our attic insulation done with Innovate Insulate and we would highly recommend. We were impressed at how fast, and tidy, the job was done and have noticed a difference in the warmth of our home. Mal and his team were friendly, helpful and quick to respond to any queries we had. In addition to this, having done some research ourselves we felt they offered the best quote for insulation and ventilation. Overall very impressed and happy with the service.

Had the attic insulated by Innovate Insulation and have to say had a great experience with them. Didn't have no clue about it before I started and decided to get a few quotes to see the market and looked up information as best I could. Had a few prices but got talking to Josh and explained everything to me and gave me a price which was the best of them all and it included the air vents. ( Witch most don't do) They were quick, clean and professional. Have to thank Josh as whatever he said he delivered. Great experience and would recommend 100%.

Innovate Insulation, Mal, Josh & Team where excellent, friendly, clean & accommodating. Initial consultation & call out was professional, informative & friendly. Our attic & hall was constantly cold & damp. Winter visits from mice! Scheduling for vents & insultation was completely organized around our finances & work life balance. I had boxes in the attic for years which the lads kindly took down so I could sort through them before they put them back up. Honestly so pleasant & helpful. Highly recommended to anyone thinking off getting insulation done. Looking forward to enjoying the full multiple benefits. We have already noticed the house is warmer and hall. Thank you from very happy customers.
