Window mastic in Newton, done properly
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you have leaking joints at the ends of sills and rushed sealant from a window installation, we can help.
In and around a place like Newton, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All our work is covered by our one-year guarantee.

Why it’s worth doing now in Newton
The work is quick compared with the damage it prevents: the visit takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- White, clear, grey or another colour, product permitting
- We are fully insured
- Sanitary silicone with an anti-fungal additive in wet areas

How the job changes by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Avoid harsh chemicals near the mastic
- Clear any debris from frame drain holes
- Keep timber frames painted
- Wash the frames with mild soapy water
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- The product the joint needs
- Whether the work is at height
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
What to tell us for a quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- Where the job is, and your postcode
- Access, such as stairs, a lift or height

There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, send an email to info@mrmastic.co.uk.
Common problems we fix in Newton
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Keep an eye out for these signs:
- Leaking joints at the ends of sills
- Rain getting in at the frame or under the sill
- Mastic that has split away from the wall
- Mastic that is falling out in pieces
Managing a site like Winchburgh Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

Common questions in Newton
Is Newton within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Dalmeny station. Can you help?
Yes, we work for landlords and agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
How much does window mastic cost in Newton?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we’re fully insured for the work.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How it works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take most of a day for a typical house, less for a few frames. Outdoor work around Newton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height

Newton homes and the weather
Newton is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Dalmeny station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Newton is about 6 miles south of Dunfermline, in West Lothian. Newton gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Our West Lothian coverage runs to 58 places, Newton among them. For nearby work, see our Edinburgh page (10 miles or so).
