DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
About our window mastic in Ashford
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Common call-outs are for cold air getting in at the frame edge and a bead that doesn’t match the frame, across patio & French doors, uPVC windows and composite doors.
Homes in small places like Ashford often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months.

What affects the quote in Ashford
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- Mould in or behind the old joints
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- The rough size of the job
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.
Leave it or put it right?
The work is quick compared with the damage it prevents: the visit takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. Around Ashford, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost 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 we start.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Your questions about window mastic in Ashford
Is window mastic in Ashford guaranteed?
All our work, in Ashford and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you do window mastic in Ashford?
Yes, Ashford is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Check the mastic once a year
- Air rooms to keep condensation down around windows
- Keep solvents and bleach off the sealant
- Use gentle cleaners on frames and sealant
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
We also work for property managers and facilities teams in Ashford and across Hampshire. We can quote a run of properties together, and we’re fully insured.
What window mastic looks like in Ashford
Historic houses like Breamore House (about 3 miles north) are a reminder that the area around Ashford has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Fordingbridge Junior School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Historic houses such as Breamore House, about 3 miles north, show how far back building around Ashford goes, and older homes nearby need a sealant that suits their walls.
