Window mastic for homes and businesses in Iwade
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on window sills, patio & French doors and timber windows & doors, and people most often call us about gaps where the sill meets the wall and untidy mastic left by window fitters.
In smaller places like Iwade, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
There’s a 12-month guarantee on every job, large or small.

What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job normally takes a few hours for a handful of frames, longer for a whole house. A visit to Iwade is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Mention any parking rules near the property
- Tell us about any water getting in
- On commercial sites, let us know about site rules

Iwade: your questions answered
Does the coastal weather in Iwade affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can you help a landlord with a rental near Kemsley station?
Yes. We work for letting agents and landlords as well as homeowners. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you reach windows above the ground floor?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Are you insured?
Yes, we are fully insured for every job we do.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.
Do you cover Iwade?
Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes Iwade.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
What affects the cost of window mastic
The price is agreed before any work begins. It’s based on:
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- When we can work, for business premises
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- How we’d reach the joints
- Where the property is
- A few pictures by email, if you can
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Rotten timber, which needs a joiner first
- Damp problems in the wall away from the window
- A door that needs adjusting, rehanging or new seals
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Windows and doors in Iwade
Iwade is within about 1 mile 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. 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 Kemsley station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Iwade School, its window and door frames need their mastic kept sound, just like a home’s.
Iwade is about 2 miles north of Sittingbourne, in Kent. From the centre of Iwade to the outskirts, window mastic is available for homes and businesses alike. Our Kent coverage runs to 922 places, and Iwade is one of them. Our Chelmsford page covers work nearby (27 miles or so).

How the job changes by surface
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
Why act early in Iwade
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a smaller place like Iwade, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Aftercare tips
So the new joints stay in good condition:
- Keep drainage slots and sill grooves clear
- Check the mastic once a year
- Do not use solvent cleaners on the joint
- Keep jet washers away from the mastic
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Signs you need window mastic in Iwade
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:
- Hard, cracked sealant around windows
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
- Rain getting in at the frame or under the sill
If you live in an older home near Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- Are they insured?
- The length of the guarantee
- When the joint can take water or movement
- Whether the sealant suits the joint
