Window & door mastic in Danaway, Kent
Mastic around window and door frames, sills and patio doors for homes and businesses in Danaway and across Kent. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps between the frame and the inside reveal
- A bead that doesn’t match the frame
- Draughts coming in around windows and doors
Window mastic in Danaway
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on timber windows & doors, patio & French doors and aluminium frames, and people most often call us about hard, cracked sealant around windows and draughts coming in around windows and doors.
Around Danaway, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What we can’t put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Faulty window hardware
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
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.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Mould in or behind the old joints
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- What’s wrong with the joints now
- The address or postcode of the job
Every job is quoted individually. Just phone 0345 464 0079 or send us an email with the details, and pictures are welcome.
Common problems we fix in Danaway
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That is what backing rod is for.
Keep an eye out for any of the following:
- Gaps where the sill meets the wall
- Draughty joints inside around the window
- Whistling draughts around closed windows
- A bead that doesn’t match the frame
Homes close to Church of St Peter and St Paul include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What to look for in a quote
- Which sealant they’ll use, and why
- How hidden problems are handled
- The length of the guarantee
- How long to leave it before use
What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere like Danaway needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

What the job involves on each surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
Work for landlords, hotels and businesses
Landlords and agents in Danaway can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
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.
Frames and glazing around Danaway
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Newington station, renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Borden Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
