How we handle window mastic in Etchingham
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have white mastic on grey or black frames and water coming in at the bottom corners of a door, we can help, whatever the surface.
Somewhere as small as Etchingham, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our one-year guarantee.

Different surfaces, different methods
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Don’t paint over the silicone
- Make sure the drainage slots aren’t blocked
- Do not aim a pressure washer at the joints
- Wipe condensation off the frames
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
FAQs for Etchingham
Is Etchingham within the area you cover?
Yes, Etchingham is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Etchingham for window mastic?
Yes, Etchingham is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can I paint over the new sealant?
Not usually, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Frames and glazing around Etchingham
With historic houses such as Bateman's (about 2.8 miles south-west) nearby, there’s older building stock in the area around Etchingham 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. 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.
If you let a flat or house near Etchingham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Etchingham Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

What else we do in Etchingham
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- Access and height
- The number and length of the joints
- Which sealant suits the joint
- When we can work, for business premises
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- The problem you’ve noticed
- Where the job is, and your postcode
- Photos by email, if that’s easy
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand.
Do you need window mastic in Etchingham?
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The problems people usually mention when they call include:
- Rushed sealant from a window installation
- Mastic that has split away from the wall
- Cold air getting in at the frame edge
- Draughty joints inside around the window
Homes close to The Parish Church of St Nicholas and St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- How the surfaces are prepared before sealing
- Are they insured?
- How hidden problems are handled
- The length of the guarantee
Why it’s worth doing now in Etchingham
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a small place like Etchingham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
