Most of the housing here is dashed render bungalows and farmhouses built to take weather, plus coastal properties on fully exposed sites. The local condition that shapes the job is the most severe in the country: Atlantic storms, horizontal rain and sustained wind loading, which is why wind loading here is a structural question, not a comfort one, and frames need fixing specifications to match.

Use the enquiry form on this page and it goes straight to them, or ring them on 086 191 7077. Ask for a measured survey before any price, get the quote in writing, and confirm who makes good the plaster inside and the render outside once the old frames come out.

Ask for a measured survey before any price, and get the quote in writing afterwards. Confirm three things in particular: whether removing and disposing of the old frames is included, who makes good the plaster inside and the render outside, and what the lead time is. Made to measure frames run six to twelve weeks, so the survey date is not the start date.

Letterkenny is in Donegal, where Errigal Windows & Glazing is registered, so yes. They work across Letterkenny, Buncrana, Ballybofey and out to Dungloe. Whether they will travel to a specific townland is worth asking directly, particularly for a smaller job.
