Excellent service from Karnheath.
Karnheath were a pleasure to deal with from the moment I contacted them. They kept in touch in a timely manner, carried out a proper survey and their work force were very helpful. They were on time, polite and tidied up after themselves. All areas of their company conducted themselves in a polite, considerate and professional manner. I can highly recommend Karnheath as a top quality business with the customer in mind.Verified reviewerJob location: NE6510 Cavity Wall Insulation

Great knowledge and flexibility
Arranged visit for quote but had to cancel due to pregnancy issues. They were super flexible and came straight out once we were back in touch. Quote was good for loft insulation and they tested for cavity wall insulation which we had. Was able to get them in the next day to top up loft insulation due to a cancellation. Super appreciated the quickness with a 3 year old and new born in the house.Verified reviewerJob location: NE12RRachael B10 Loft Insulation

Review and Refill Existing Insulation
Karnheath arranged the assessment of my failing cavity wall insulation very quickly and found some areas to have pockets of insulation missing. They then came and carried out the works to repair and top up the insulation. All works were carried out quickly and professionally and guarantee received.Verified reviewerJob location: DH1
