Why book with us in Clevedon
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
No pressure selling
You get everything in writing and decide in your own time.
Honest about grants
If you might qualify for funding, we tell you before we quote.

Questions about a loft insulation top-up in Clevedon
Can you visit Clevedon outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Can a landlord in Clevedon book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do you charge extra to travel to Clevedon?
Not normally. Our guide prices include normal travel to Clevedon. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can new insulation go on top of old insulation?
Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.
Is it worth topping up 100 mm of loft insulation?
Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.
