How we handle window mastic in Musselburgh
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. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for gaps between the frame and the inside reveal and white mastic on grey or black frames, across uPVC windows, aluminium frames and timber windows & doors.
In a town like Musselburgh, stone-built older streets usually sit alongside harled houses and newer estates, and windows range from older sash and case to modern uPVC. The sealant has to suit both the frame and the wall it sits in.
Big or small, it’s backed by our 12-month guarantee.

Why it’s worth doing now in Musselburgh
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In Musselburgh, wind and rain soon get through failed outside joints. Indoors, failed sealant lets water into floors and ceilings.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

What affects the cost of window mastic
Jobs vary more than people expect. What affects the quote:
- How many areas need sealing
- The size of the job
- Whether old sealant or filler has to be cut out
- Access and height
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- A few photos by email, if you can
- Whether it’s a home or a business
To get a quote, send an email to info@mrmastic.co.uk with the location and a short description of the problem. You’ll have a clear quote before any work starts.
What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Questions from Musselburgh
Can you help a landlord with a rental near Musselburgh station?
Yes, we work for landlords and letting agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Is window mastic in a coastal place like Musselburgh any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
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 do one or both.
Work for landlords, hotels and businesses
If you manage several properties in or around Musselburgh, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
When something else is needed
New sealant can’t fix everything, and we will tell you before we start. It won’t solve:
- Soft or decayed wood in the frame
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.
Joints and surfaces we work on
- uPVC windows
- Composite doors
- Timber windows & doors
- Aluminium frames
- Patio & French doors
- Window sills
When to call us in Musselburgh
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Look out for any of the following:
- Gaps between the frame and the inside reveal
- Hard, cracked sealant around windows
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
For landlords with property near Musselburgh station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes most of a day for a typical house, less for a few frames. For a job in Musselburgh, tell us where the work is, how to get in and where to park. Outside work depends on the weather, as sealant needs a dry surface.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

Advice
Musselburgh homes and the weather
Musselburgh is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Hamilton House (about 3.1 miles east) are a reminder that the area around Musselburgh has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Loretto School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Historic houses such as Hamilton House, about 3.1 miles east, show how far back building around Musselburgh goes, and older homes nearby need a sealant that suits their walls.
