Window & door mastic in Blackness, West Lothian
Our applicators work in Blackness on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.

Window mastic in Blackness, done properly
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. If you have draughty joints inside around the window and rain getting in at the frame or under the sill, we can put it right, whatever the surface.
In and around a place like Blackness, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What we’re called out for in Blackness
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
It’s worth asking for a quote if you see:
- Black, perished sealant on frames
- Draughts coming in around windows and doors
- Leaking joints at the ends of sills
- Draughty joints inside around the window
If you let a flat or house near Linlithgow station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Whether all the old sealant comes out first
- How the colour is chosen
- Whether the sealant suits the joint
- Whether VAT is included

What else we do in Blackness
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Air rooms to keep condensation down around windows
- Make sure the drainage slots aren’t blocked
- Keep solvents and bleach off the sealant
- Keep timber frames painted
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
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.
What affects the cost of window mastic
We do not publish a price list, because jobs vary so much. What we look at:
- Working hours on commercial sites
- The old material and how stubborn it is
- How much there is to do
- The type of sealant required
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs
- Where the property is
- How many joints, rooms or windows are involved
- A few pictures by email, if you can

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Blackness homes and the weather
Blackness 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 failed outside joints work against that.
Around Blackness, as everywhere, window mastic is only as good as the preparation behind it.
Blackness is about 3 miles east of Bo'ness, in West Lothian. Wherever you are in the EH49 postcode area, we can carry out window mastic at your property. Our West Lothian coverage runs to 58 places, and Blackness is one of them. There’s also a page for Edinburgh, roughly 13 miles from Blackness.
We cover every part of the EH49 postcode area for window mastic. Close by, we work in Muirhouses (2 miles west), Charlestown (2 miles north), Crombie (3 miles north), Cairneyhill (4 miles north) and Torryburn (4 miles north-west). Further out, we also cover Livingston (7 miles south), Bathgate (9 miles south-west), Linlithgow (4 miles south-west), Whitburn (12 miles south-west), East Calder (8 miles south) and Broxburn (5 miles south).
Landmarks near Blackness
The nearest railway station is Linlithgow station, roughly 3.4 miles south-west of the centre. Well-known places in the area include Blackness Castle (less than half a mile north-east) and Boness Motor Museum (2.7 miles west). Green spaces nearby include Linlithgow Loch.
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a place like Blackness, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

Different surfaces, different methods
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It usually takes a morning for a couple of windows and a door. Outdoor work around Blackness depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, we confirm safe access to each frame.
- 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.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Mention if the joints have been sealed before

Your questions about window mastic in Blackness
I let a flat near Linlithgow station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Is window mastic in a coastal place like Blackness any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Do you guarantee window mastic?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
How many windows can you do in a day?
Allow anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you cover Blackness?
Yes, we do. Our applicators work in Blackness, and the service is the same as everywhere else.
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.
