Damaged lath repairs in Derry/Londonderry: questions

How much is a visit in Derry/Londonderry?

Prices for damaged lath repairs start from £149 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Derry/Londonderry as elsewhere we cover.

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

What should I do while I wait for a visit in Derry/Londonderry?

If the door is stuck part-open, keep people, pets and cars clear of it and switch off the power at the isolator if it is safe to reach. Do not force the curtain or open the roller box. Your Derry/Londonderry visit date is confirmed in writing.

Can I message you a photo of my garage in Derry/Londonderry?

Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Derry/Londonderry. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

My car hit the garage door. Can I still use it?

If the curtain is out of its guides, running at an angle or catching as it moves, stop using it. Switch an electric door off at the isolator, keep people and cars clear of a part-open door, and don't force the curtain. Take photos and request a visit so the engineer can check the laths, guides and motor.

Can you replace just one lath on a roller garage door?

Yes, if the rest of the curtain is sound and a matching lath is available. The damaged lath is slid out, a new one with the same profile is fitted, and the curtain is refitted and run through its guides. Photos of the damage and the lath ends help us confirm what's needed before booking.
