About our window mastic in Worth
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on timber windows & doors, patio & French doors and composite doors, and people most often call us about cracked internal joints between frame and plaster and mastic that’s falling out in pieces.
Around Worth, 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.
Whatever the size of the job, you get the same 12-month guarantee in Worth and across Kent.

Do you need window mastic in Worth?
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Look out for any of the following:
- Black, perished sealant on frames
- Rushed sealant from a window installation
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
For landlords with property near Sandwich station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the visit works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a morning for a couple of windows and a door. In a small place like Worth, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Your questions about window mastic in Worth
Is window mastic in a coastal place like Worth any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Sandwich station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Surface by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Honest limits
To be straight with you, some problems need a different trade:
- Draughts through the window seals rather than the frame
- Soft or decayed wood in the frame
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

What window mastic looks like in Worth
Worth is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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 Walmer Castle (about 4.5 miles south-east) are a reminder that the area around Worth has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to Church of St Peter and St Paul include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Worth Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints
After the cure time, these simple habits help:
- Don’t aim a pressure washer at the joints
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Don’t use solvent cleaners on the joint
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
