How window mastic works in Midlothian
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for gaps where the sill meets the wall and untidy mastic left by window fitters, on aluminium frames, composite doors and patio & French doors.
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job normally takes most of a day for a typical house, less for a few frames, and we explain the cure time before we leave.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

Around Bonnyrigg
Locally, jobs take us to homes and businesses close to Bonnyrigg Parish Church, Lasswade High School Centre and Public Library. The nearest railway station is Eskbank station, about 1.1 miles north-east. A little further out are Dalhousie Castle (1.2 miles south-east) and Midlothian Community Hospital (0.8 miles north-east). The countryside around Bonnyrigg includes The New Leaf Co-op and Edgelaw Reservoir.
Windows and doors across Midlothian
Across Midlothian, from Bonnyrigg, Dalkeith and Penicuik outwards, frames range from older timber to modern uPVC and aluminium. Each needs the right sealant, and every joint wears out eventually.
Scottish weather is hard on outside joints, especially in the wetter west. Sealants for jobs in Midlothian are chosen with that in mind. In the coastal parts of Midlothian, the sea-facing side of a building takes the most weather, so they’re often the first to fail. The right product and careful preparation help it last.
Bonnyrigg: Homes close to Bonnyrigg Parish Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Lasswade High School Centre, the mastic around its windows and doors needs looking after like any other building’s.
Landlords, agents and businesses in Midlothian
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Faulty window hardware
- Soft or decayed wood in the frame
- Worn gaskets, brush seals or a door that has dropped
How we quote for window mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- The product the joint needs
- The size of the job
- The number of rooms or windows
- Access and height
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- Where the property is
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.
What happens if it’s left?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost.
What your quote should include
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- How much experience the applicator has
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep drainage slots and sill grooves clear
- Don’t use solvent cleaners on the joint
- Keep timber frames painted
- Air rooms to keep condensation down around windows
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
FAQs for Midlothian
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before we start.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Do you work for letting agents?
Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
