I had difficulty finding a reputable tradesperson for external wall insulation on a solid wall. I chose an EWI specialist with many five-star reviews. After a site visit and a detailed quote from Sebastian, I trusted their professionalism. They completed the project on time, showing reliability, professionalism, and integrity. Sebastian was courteous, maintained excellent communication, and addressed issues quickly with expert advice. I highly recommend their services for rendering or EWI projects. Thanks to Sebastian and his team for successfully finishing the work on my property.

I found EWI by using a Google search, they were in touch the same day and arrived to look at the property the same week. Sebastian was helpful and knowledgeable, and the works began earlier than we were expecting. The personalised service we received was outstanding. Communicating with the team was easy and straight forward. The additional works regarding the facias, sofits and gutters were no hassle at all. I would highly recommend EWI specialist.

We originally wanted this done for helping to resolve all the condensation issues you have with a solid wall house. It seems that the house was warmer since the insulation was applied about day 2 or 3. The work team were fast and hardworking. There was no loud radio going just the basic construction noise which was the first few days. They were always prompt arriving and the job really had momentum. The appearance of my property has drastically improved as the guys retained some of the classic features with the use of creating form and applying brick slips and paint. Initially I had been quoted for just a silicone render but this worked out less expensive and has the insulation too. Im very pleased with the appearance and look forward to warmer winters indoors too. Thank you Guys

Sebastian and his team have been wonderful in completing our project in the timeline and cost that was agreed. A formal contract was given detailing the scope of work, time frame and cost. Sebastian arrived on time for initial consultation and I explained that ours was a two part project as we had scaffolding in the way which could only be removed once the 1st floor insulation and render was completed. Sebastian took our considerations into planning and communicated this with his employees. Work was completed quickly and efficiently by Daniel, Karol and another. All of Sebastian's site employees were kind, considerate and arrived on time each day to work and left our property clean and tidy. The office staff have been great in supplying the U value documentation for LBC along with the guarantees as detailed.
I highly recommend EWI Specialist for anyone wishing to have works carried out by Sebastian & his team.

We used EWI to insulate 2 large exterior walls and then render a new porch to give the whole house a facelift. The team worked really hard, they were respectful, the communication with Sebastian and the office was great and we are delighted with the outcome. I would thoroughly recommend EWI to anyone considering exterior insulation. Great company, excellent work!
