Questions about a loft insulation top-up in Tewkesbury
Will I get a written quote for work in Tewkesbury?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you charge extra to travel to Tewkesbury?
Not normally. Our guide prices include normal travel to Tewkesbury. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Is loft work in Tewkesbury different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
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.
Can I still store things in the loft after a top-up?
Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
