    Thank you for your review submitted on Feefo.

    I believe you gave it fewer stars than any other customer, so we are disappointed that you are disappointed with Extraglaze.

    Service rating : We didn't fit the panels straight away so I hadn't noticed the fitting instructions were missing. Richard Greenland, the director, sent these a few days later with an apology that they had been left out of the parcel.

    We were kept informed of the progress of our order,...

Fitting

 

 Extraglaze Fitters improve window insulation and soundproofing

The benefits of installing secondary glazing over replacing your existing windows are:

• Usually fitted in a day

• Minimal disruption

• No huge openings while the replacements go in

• No re-plastering or redecoration (unless frame painting is required)

• No planning issues

• Preserve the beauty and character inside and out

• We rarely need to use power tools during installation

 

As well as all the benefits above, Extraglaze is nearly always supplied and fitted at considerably less expense than replacements.

 

While we are in your property

Our approved fitter will arrive with your made-to-measure Extraglaze panels. We will wipe down some of the window frame paintwork, then unwrap and apply the Extraglaze panels in quite rapid succession. On some windows, especially sash windows, we may fit additional components, all quite minimalist. There may be a need for some power tools, but not many. A ladder and small platform may be used to reach high. Any “mess” made during installation is mostly limited to our packaging and protective materials which will be taken away.
