Window & door mastic in Canewdon, Essex
Our applicators work in Canewdon on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
- Water coming in at the bottom corners of a door
How we handle window mastic in Canewdon
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. We work on composite doors, window sills and aluminium frames, and common reasons people get in touch are cold air getting in at the frame edge and rain getting in at the frame or under the sill.
Somewhere as small as Canewdon, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All our work is covered by our one-year guarantee.

How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Clean frames with a soft cloth and soapy water
- Air rooms to keep condensation down around windows
- Don’t use solvent cleaners on the joint
- Keep timber frames painted
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
What we’re called out for in Canewdon
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Any of these means the joints need attention:
- Cold air getting in at the frame edge
- Gaps where the sill meets the wall
- Black, perished sealant on frames
- Untidy mastic left by window fitters
Managing a site like King Edmund School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Window mastic in Canewdon: local notes
Rainfall in the South East is lower than in much 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 Althorne 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 Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What else we do in Canewdon
Leave it or put it right?
The work is quick compared with the damage it prevents: it takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. Around Canewdon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

FAQs for Canewdon
Will you come out to Canewdon?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Althorne station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes most of a day for a typical house, less for a few frames. Somewhere as small as Canewdon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
