Window mastic for homes and businesses in Finglesham
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for rushed sealant from a window installation and draughts coming in around windows and doors, on aluminium frames, uPVC windows and patio & French doors.
In a village or hamlet like Finglesham, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You get a one-year guarantee, the same in Finglesham as everywhere else we work.

Surface by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What we are called out for in Finglesham
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Signs it’s time to call us include:
- A bead that does not match the frame
- Rushed sealant from a window installation
- Water coming in at the bottom corners of a door
- Gaps between the frame and the inside reveal
Rented homes near Sandwich station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- How the joint is cleaned and prepared
- What guarantee comes with the work
- Are they insured?
- Is the old sealant removed completely?
What we can’t put right
A few problems are outside what sealant work can do:
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Windows and doors in Finglesham
Finglesham is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Walmer Castle (about 3.4 miles south-east) nearby, there’s older building stock in the area around Finglesham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to Church of St George include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Northbourne Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Use gentle cleaners on frames and sealant
- Keep paint and stain on wooden frames in good order
- Keep jet washers away from the mastic
- Make sure the drainage slots are not blocked
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
