Questions about a loft insulation top-up in Dungiven
Can a landlord in Dungiven 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 Dungiven?
Not normally. Our guide prices include normal travel to Dungiven. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
What do I need to do before you arrive in Dungiven?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
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.
