Window Mastic in Frittenden
We cover Frittenden for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
- Cold air getting in at the frame edge
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, 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 call for the right materials, safe access and experience.
How we handle window mastic in Frittenden
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We are often asked to deal with a bead that doesn’t match the frame and old mastic that has gone black or come away, across uPVC windows, window sills and patio & French doors.
Around Frittenden, 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.
Our work is backed for twelve months.

How it works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a morning for a couple of windows and a door. For a village or hamlet like Frittenden, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.

Quotes for window mastic in Frittenden
There’s no set price list, because no two jobs are the same. The quote depends on:
- Any mould that needs treating
- Any working-time requirements on site
- The type of sealant required
- The number of rooms or windows
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- How we’d reach the joints
- The address or postcode of the job
- Photos by email, if that’s easy
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Repaint timber before it’s bare
- Wipe condensation off the frames
- Avoid blasting the frames with a pressure washer
- Do not use solvent cleaners on the joint
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
Why it’s worth doing now in Frittenden
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a small place like Frittenden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Common questions in Frittenden
I let a flat near Headcorn station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Will you come out to Frittenden?
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.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Can I do it myself?
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 work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How the job changes by surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. We use a neutral-cure product.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Windows and doors in Frittenden
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Headcorn station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Frittenden Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
