Door fitting in Tranent and East Lothian
We fit doors throughout the house, from a single new bedroom door to a full set of internal doors, and from a new front door to a back or side door. Each one is hung and finished by hand so it opens and closes cleanly in your opening, even in older homes where nothing is quite square.
Internal doors fitted in East Lothian often mean matching a whole house. If you want one design and finish throughout, with matching handles and hinges, we can fit the lot in one go. Solid-core doors are a popular choice where you want better sound insulation, for example in a busy household or a home office.
- Internal doors, including glazed doors to share light between rooms
- External doors, front, back and side
- Fire doors, fitted to suit the opening
- Adjusting, re-hanging and repairing doors that stick or drop
Sash window repair in Tranent and East Lothian
Old timber and sash windows can often be repaired rather than replaced. Typical jobs include windows that rattle, stick or won't stay open, and rotten sections of timber that need cutting out and replacing. Keeping the original window usually keeps the look of the house too.
Repair is also the simplest route if your home is in a conservation area or is listed. East Lothian Council's heritage guidance says replacing windows in a conservation area needs planning permission unless the new window matches the existing one exactly, and listed buildings need Listed Building Consent. The same guidance says repairing existing windows does not require consent. If you are unsure, check with the council before work starts.
Do I need a building warrant for a new door or window?
In Scotland you apply for a building warrant (not building regulations approval). Generally, a warrant is needed for work on an external wall to install a new door or window, with a straight replacement within the existing opening being the usual exception. Making an opening bigger or smaller, or cutting a new one, normally needs a warrant.
Installer guidance varies on window replacements, so we always suggest confirming your own case with East Lothian Building Standards before work begins. Working without a warrant where one is required is an offence under the Building (Scotland) Act 2003. Energy standards also apply to replacement windows, and one installer guide puts the figure at a U-value of 1.4 W/m²K or better, so ask any installer how they show compliance. Schemes such as FENSA cover England and Wales, not Scotland.
We will tell you honestly what we think applies to your job at the first visit, and point you to the council for the final answer.

Choosing styles and finishes
For external doors and windows, the trends suppliers mention for 2026 include darker greys, soft greens and woodgrain finishes, and slimmer frames. For heritage homes, timber is still the natural match. Inside, black doors, natural oak and walnut tones, and shaker and flush styles are all popular. Treat this as a guide only, as much of it comes from suppliers.
We are happy to talk through what suits your house, and you can see our recent fitted work on the recent work section of our site.

Questions we're asked.
Do I need a building warrant to replace a door or window in East Lothian?
A straight replacement within the existing opening is generally the exception, but a new door or window in an external wall, or changing the size of an opening, usually needs a building warrant. Guidance differs between sources, so confirm your case with East Lothian Building Standards. We can talk it through at your free estimate.
Can sash windows be repaired instead of replaced?
Often, yes. Rotten timber can be cut out and replaced, and windows that stick, rattle or won't stay open can usually be put right. East Lothian Council's guidance says repairing existing windows does not need consent, which makes repair the simplest option in conservation areas and listed buildings.
Do you fit internal and fire doors as well as front doors?
Yes. We fit internal doors, external doors and fire doors, and we can fit a matching set through the whole house. We also adjust and re-hang doors that stick or drop. Tell us what you have in mind and we will advise at the visit.
Can I replace windows in a conservation area?
East Lothian Council's guidance says planning permission is needed to replace windows in a conservation area unless the new window matches the existing one exactly. Listed buildings need Listed Building Consent. Check with the council first, and ask us if repairing your existing windows is an option.
