Questions about a loft insulation top-up in Twickenham

Is loft work in Twickenham 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.

Do you charge extra to travel to Twickenham?

Not normally. Our guide prices include normal travel to Twickenham. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Can a landlord in Twickenham book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

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 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.
