Window mastic for homes and businesses in Felderland
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on timber windows & doors, aluminium frames and patio & French doors, and common reasons people get in touch are cracked sealant at the sill ends and rain getting in at the frame or under the sill.
Mastic can only go onto a dry, clean joint, so window work in Felderland is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months.

Should I try it myself first?
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, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What happens on the day
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take most of a day for a typical house, less for a few frames. In a small place like Felderland, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Wipe condensation off the frames
- Keep drainage slots and sill grooves clear
- Keep paint off silicone joints
- Do not aim a pressure washer at the joints
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Felderland homes and the weather
Felderland is close to 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. With historic houses such as Goodnestone Park (about 4.7 miles west) nearby, there’s older building stock in the area around Felderland as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Schools such as Sandwich Technology School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Sandwich station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of St Peter and St Paul, the joint between an old wall and a newer frame is normally the first place rain gets in.

FAQs for Felderland
Will you come out to Felderland?
Yes, Felderland is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Felderland affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Can you do upstairs windows?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
Landlords, agents and businesses in Felderland
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
If you manage several properties in or around Felderland, several properties can go on one quote. Just tell us the addresses and what each one needs.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Felderland, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
