Dormer Window Repairs — indicative geometry

Dormer Window Repairs for Angus and Dundee homes

The housing stock around Angus and Dundee runs to Victorian and Edwardian terraces, interwar semi-detached houses and post-war bungalows — so the first question at survey is always which of those you have, because the structure underneath differs completely.

A stain on a dormer ceiling almost never starts at the window. It usually starts at the apron flashing, the cheek-to-roof soaker, the back gutter or a split in the flat roof covering, and travels. We trace the actual water path before quoting, because replacing a window that was never leaking is the most common wasted spend on a dormer.

Planning and building control in Angus and Dundee

Whether you need planning permission or a lawful development certificate depends on the elevation, the volume already used and the local authority's Article 4 position — all of which we confirm before design work starts.

Building regulations approval is separate and always required. We submit the application, book the inspections around the programme and hand you the completion certificate at the end — the document a buyer's surveyor will ask to see.

FAQs

Dormer Window Repairs in Angus and Dundee — FAQs

What is the difference between a dormer and a Velux?

A rooflight sits flush in the roof slope and gives you light without any extra height — you still have a sloping ceiling. A dormer projects out from the roof and creates vertical walls with a level ceiling behind them, so you gain genuinely usable standing space and floor area, not just daylight.

Do you work on listed buildings and in conservation areas?

Yes. That work is detail-led: matching sightlines, glazing bar widths, cill projections and cheek finishes to what survives, and specifying timber, lead and natural slate rather than modern equivalents. We prepare the drawings and heritage statement for listed building consent alongside the planning application.

Can a dormer include an en-suite?

Very often, yes — a full-width or L-shaped dormer usually has enough floor area for a bedroom plus a shower room. The practical constraints are getting soil and waste down to an existing stack, and whether the head height over the shower tray works. Both are settled at survey.

What happens to my existing loft insulation?

It comes out. Insulation at ceiling-joist level is in the wrong place once the loft is a room — the thermal line moves up to the new roof and dormer build-up. We remove and dispose of the old quilt and insulate the new envelope, which is also what makes the room comfortable to use in August.

How long does a dormer take to build?

A single box or flat roof dormer is typically three to five weeks on site. A full-width rear dormer runs five to eight weeks, and an L-shaped dormer on a terrace with an outrigger is closer to seven to ten. A complete dormer loft conversion including the staircase, services and finishes is usually eight to twelve weeks from scaffold up to sign-off.
