Different surfaces, different methods
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
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.
About our window mastic in Westfield
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, drop us a line at info@mrmastic.co.uk with the number of frames and any access details. If you’re dealing with rushed sealant from a window installation and damp patches on the reveal after heavy rain, we can put it right, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Westfield depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

What affects the cost of window mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The type of sealant required
- Access and height
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
To make quoting easier, let us know:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes most of a day for a typical house, less for a few frames, depending on how much there is to do. For a place like Westfield, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
Ask for a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand.

Landlord and commercial work in Westfield
For anyone letting property in or around Westfield, several properties can go on one quote. Send us the addresses and the work at each.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep paint off silicone joints
- Do not use solvent cleaners on the joint
- Air rooms to keep condensation down around windows
- Do not aim a pressure washer at the joints
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just email us at info@mrmastic.co.uk.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Questions from Westfield
Is Westfield within the area you cover?
Yes, Westfield is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Croy station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How do I get a quote for window mastic in Westfield?
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. We agree the price before any work begins.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
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.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Honest limits
We’ll always be straight with you, so here’s what new sealant will not do:
- A door that needs adjusting, rehanging or new seals
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Rotten timber, which needs a joiner first
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- Window sills
- Timber windows & doors
- uPVC windows
- Aluminium frames
- Patio & French doors
- Composite doors
What window mastic looks like in Westfield
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Managing a site like Greenfaulds High School? Then the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Croy station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
