Mastic around window and door frames, sills and patio doors for Stenton, backed by a one-year guarantee. Call for a quick quote.

- Sealant in the wrong colour for the frame
Window mastic in Stenton, done properly
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you have cracked or shrunken mastic around the frame and sealant in the wrong colour for the frame, we can help, on timber windows & doors, patio & French doors and window sills alike.
Mastic can only go onto a dry joint, so outside work in Stenton depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
There’s a 12-month guarantee on every job.

Landlord and commercial work in Stenton
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.
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.
What window mastic looks like in Stenton
Stenton is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near Stenton Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

When something else is needed
To be straight with you, some problems need a different trade:

- Faulty window hardware
- A failed sealed unit that has misted up

- Composite doors
- Window sills
- Aluminium frames
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work
- Move anything stored near the joints

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep paint and stain on wooden frames in good order
- Wash the frames with mild soapy water
- Don’t paint over the silicone
- Wipe condensation off the frames
Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What affects the quote in Stenton
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- The problem you’ve noticed
- Roughly how big the job is
- A few photos by email, if you can
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
Stenton questions
Can you help a landlord with a rental near East Linton station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Does the coastal weather in Stenton affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
What should I tell you?
Tell us what needs doing and where. If we need more, we will ask.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
How do I get a quote for window mastic in Stenton?
We do not publish prices, because the cost 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 we start.
Signs you need window mastic in Stenton
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Draughts coming in around windows and doors
- A bead that does not match the frame
- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
For landlords with property near East Linton station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before booking
- How the colour is chosen
- Whether they’re fully insured
- Whether they seal over old material or remove it
- Whether the sealant suits the joint
Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
