Window mastic for homes and businesses in Ashford
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We are often asked to deal with mastic that has split away from the wall and cracked internal joints between frame and plaster, across window sills, aluminium frames and uPVC windows.
In a town like Ashford, the windows on the most exposed side of a house take the brunt of the rain, so the mastic there tends to fail first. Checking every frame, not just the obvious one, is time well spent.
All our work is covered by our one-year guarantee, wherever you are in Surrey.

Ashford homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Ashford Surrey station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Parish Church of St Matthew, the joint between an old wall and a newer frame is usually the first place rain gets in.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
How we quote for window mastic
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- When we can work, for business premises
- The number and length of the joints
- Mould in or behind the old joints
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
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:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- The address or postcode of the job
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or send us an email.
Why deal with it now?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. In a family home in Ashford, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why book with us
- Arbo and Everbuild products
- We are fully insured
- Old sealant always removed completely

When to call us in Ashford
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Signs it’s time to call us include:
- Black, perished sealant on frames
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
If you look after a building such as Spelthorne College, the mastic around its windows and doors needs looking after like any other building’s.

Ashford questions
Can you help a landlord with a rental near Ashford Surrey station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Is Ashford in your area for window mastic?
Yes. Our work covers London and the South East, and Ashford is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Are you fully insured?
Yes, we’re fully insured.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Do you work on first-floor windows?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
What we cannot put right
To be straight with you, some problems need a different trade:
- Rotten timber, which needs a joiner first
- A door that needs adjusting, rehanging or new seals
- A failed sealed unit that has misted up
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Window sills
- uPVC windows
- Patio & French doors
- Aluminium frames
- Composite doors
- Timber windows & doors
How the job changes by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes most of a day for a typical house, less for a few frames. In Ashford, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Mention any parking rules near the property
- Move anything stored near the joints
- Mention any tricky access
