Glazing bar and capping repairs in Lerwick

If you're in Lerwick and dealing with a lifted capping or perished gasket, we can help. We re-seat or replace lifted cappings, perished gaskets and loose glazing bar fixings, and confirm the fixed price in writing before we start.

We carry out glazing bar and capping repairs in Lerwick and across the ZE1 area. Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets.

What you might be seeing

  • A capping visibly higher than its neighbours
  • Water running down one glazing bar inside
  • Rattling or whistling in wind

Common causes we find

Gasket shrinkage

Rubber gaskets shrink back from the ends over time, leaving a gap at the ridge or eaves.

Damage

Ladders, window cleaning or someone stepping on a lantern can bend a capping or unclip it.

About Lerwick and the ZE1 area

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

We cover Lerwick by arrangement: island work is planned around ferry access, and any travel or access costs are set out in your written quote before you commit.

How much should it cost?

Guide price, per lantern£165–£395 ex VAT£198–£474 inc VAT

Typical range: £165–£395 ex VAT, which is £198–£474 with VAT, per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.

Do you need permission in Scotland?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
