Window mastic in Ashfield
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on uPVC windows, timber windows & doors and composite doors, and people most often call us about gaps left after new windows were fitted and mastic that’s falling out in pieces.
Homes in small places like Ashfield often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Ashfield questions
Is window mastic in a coastal place like Ashfield any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Romsey station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
How do I get a quote for window mastic in Ashfield?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Are you fully insured?
Yes. We’re fully insured for every job we do.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
How long will my window job take?
The work takes a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a small place like Ashfield, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Surface by surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Composite doors
Front doors take the weather head on. We pay most attention there.
What else we do in Ashfield
The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a morning for a couple of windows and a door. In a small place like Ashfield, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Keep children and pets away from the work area
- Clear the area around the work
- Let us know about parking restrictions

Advice
How we quote for window mastic
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- The number and length of the joints
- Access and height
- Any mould that needs treating
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
To help us quote quickly, please include:
- Where the property is
- Pictures of the joints, sent by email
- The rough size of the job
- Whether it’s a home or a business
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand.
For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Ashfield homes and the weather
Ashfield is within about 3 miles 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. Historic houses like South Stoneham House (about 4.8 miles east) are a reminder that the area around Ashfield has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Boniface, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Romsey station, renewing tired window mastic between tenants heads off draught and damp complaints.

What we are called out for in Ashfield
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That is what backing rod is for.
These are the problems we’re asked about most:
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- A bead that does not match the frame
- Black, perished sealant on frames
Managing a site like Oasis Academy Lord's Hill? Then its window and door frames need their mastic kept sound, just like a home’s.
