Window mastic in Whitfield
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We work on patio & French doors, window sills and composite doors, and the jobs we see most are damp patches on the reveal after heavy rain and draughts coming in around windows and doors.
Homes around Whitfield range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What window mastic looks like in Whitfield
Whitfield is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Whitfield Aspen School, the mastic around its windows and doors needs looking after like any other building’s.

What affects the quote in Whitfield
You’ll get a clear quote before we start. It’s based on:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Mould in or behind the old joints
- How easy the joints are to reach
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- The problem you’ve noticed
- Photos by email, if that’s easy
- The type of property
- Any previous sealing or DIY work
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
Common questions in Whitfield
I let a flat near Kearsney station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Does the coastal weather in Whitfield affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you reach windows above the ground floor?
Normally, yes. We plan safe access before the job, so mention the height and anything in the way.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
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.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you come to Whitfield?
Yes, we do. Whitfield is part of the area we cover.
What the job involves on each surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Landlords, agents and businesses in Whitfield
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What we are called out for in Whitfield
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
People usually contact us after spotting one of these:
- Black, perished sealant on frames
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
- Gaps between the frame and the inside reveal
Rented homes near Kearsney station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Before you book anyone
- Whether VAT is included
- Whether they’re fully insured
- Who does the work, and how experienced they are
- Which sealant they’ll use, and why
DIY sealant or a professional job?
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. All the old material has to come out first.
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.

- Deep gaps are filled with backing rod to set the depth.
