Window mastic for homes and businesses in Great Saling
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on uPVC windows, patio & French doors and timber windows & doors, and people most often call us about mastic that’s falling out in pieces and hard, cracked sealant around windows.
Around Great Saling, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
There’s a 12-month guarantee on every job, whatever its size.

What happens if it’s left?
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Where a wall is exposed, as many are in small places like Great Saling, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Great Saling, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- 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
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Related advice
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we are called out for in Great Saling
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
- Mastic that’s falling out in pieces
- Gaps where the sill meets the wall
Letting a property close to Braintree station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- How the surfaces are prepared before sealing
- Is VAT in the price?
- What the cure time is
- How hidden problems are handled
When something else is needed
In fairness, there are a few things sealant will not fix:
- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Window sills
- Timber windows & doors
- Patio & French doors
- Composite doors
- uPVC windows
- Aluminium frames
How the job changes by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
What affects the cost of window mastic
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- The type of sealant required
- Whether the work is at height
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- Roughly how big the job is
- The address or postcode of the job
We do not publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, call 0345 464 0079 or email us.
Common questions in Great Saling
Can you do window mastic in Great Saling?
Yes. Our work covers London and the South East, and Great Saling is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Great Saling?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do upstairs windows?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where are you based?
Mr Mastic is based in Crawley. We cover Great Saling and the rest of Essex.
Frames and glazing around Great Saling
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St James include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
