Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a place like Borgh, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Why us?
- Anti-fungal sanitary silicone in wet areas
- You choose the colour before work begins
- 20+ years of sealant experience
- 4.9 on Google from 180+ five-star reviews

Window mastic in Borgh
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, send an email to info@mrmastic.co.uk with the number of frames and any access details for window mastic in Borgh. If you have rain getting in at the frame or under the sill and a bead that doesn’t match the frame, we can put it right, on patio & French doors, window sills and timber windows & doors alike.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

FAQs for Borgh
Does living near the coast affect window mastic in Borgh?
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.
Do you cover Borgh for window mastic?
Yes, Borgh is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Do you guarantee window mastic?
Yes. Our 12-month guarantee covers every job.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
How the visit works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes most of a day for a typical house, less for a few frames. Around Borgh, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

What we cannot put right
Before booking, it’s worth knowing the limits:
- Broken hinges, locks or handles
- Damp problems in the wall away from the window
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal
- Aluminium frames
- Window sills
- Patio & French doors
- Composite doors
- uPVC windows
- Timber windows & doors
What the job involves on each surface
Composite doors
Front doors take the weather head on. Those corners get the most care.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
When to call us in Borgh
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
It’s worth asking for a quote if you see:
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
- Cracked internal joints between frame and plaster
Whether the job is in Borgh itself or nearby, the right material for each joint matters as much as a neat finish.

DIY sealant or a professional job?
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 are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
How we quote for window mastic
Jobs vary more than people expect. The main factors:
- Whether there’s mould to deal with
- Whether the work is at height
- Which sealant suits the joint
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- A few photos by email, if you can
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
For a quote, email us at info@mrmastic.co.uk with the location and a short description of the problem. You will have a clear quote before work begins.
What window mastic looks like in Borgh
Borgh 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
Around Borgh, as everywhere, window mastic is only as good as the preparation behind it.
