Teynham Street Window Mastic
Professional window mastic in and around Teynham Street, with old sealant always removed completely.
- A bead that does not match the frame
- Gaps where the sill meets the wall
- Water coming in at the bottom corners of a door
When it isn’t the sealant
New sealant cannot fix everything, and we’ll tell you before we start. It won’t solve:
- Penetrating damp from a failed cavity tray or render
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- uPVC windows
- Window sills
- Patio & French doors
- Timber windows & doors
- Aluminium frames
- Composite doors

Leave it or put it right?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Teynham Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
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.

Window mastic in Teynham Street: local notes
Teynham Street is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Teynham station, renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the visit works
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work usually takes a morning for a couple of windows and a door. For a village or hamlet like Teynham Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Advice
Do you need window mastic in Teynham Street?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Keep an eye out for any of the following:
- Gaps where the sill meets the wall
- Mastic that has split away from the wall
- Cold air getting in at the frame edge
- Draughty joints inside around the window
Schools such as Teynham Parochial Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- Which sealant they’ll use, and why
- Is VAT in the price?
- How the surfaces are prepared before sealing
- How hidden problems are handled
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
How we quote for window mastic
Your quote is based on your job. We look at:
- Whether the work is at height
- Any working-time requirements on site
- How much there is to do
- Whether there’s mould to deal with
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- Where the property is
If you are in Teynham Street and need window mastic, call 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you’ll get a clear quote before any work starts.
