Window Mastic in Hellingly
Window and door frames in Hellingly need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Rushed sealant from a window installation
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a few frames, or a day or more for a whole house. Parking around Hellingly is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work

Window mastic for homes and businesses in Hellingly
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 aluminium frames, uPVC windows and patio & French doors, and people most often call us about mastic that has split away from the wall and mastic that’s falling out in pieces.
In a smaller place like Hellingly, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
Your job is guaranteed for a year, as with all our work.

Why it’s worth doing now in Hellingly
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Homes in smaller places like Hellingly can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
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.

What affects the cost of window mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- How many rooms, windows or areas are involved
- The type of sealant required
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- The rough size of the job
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Joints and surfaces we work on
- Aluminium frames

Landlord and commercial work in Hellingly
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Landlords and agents in Hellingly can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
When to call us in Hellingly
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
If you can see any of these, it’s time to have the joints looked at:
- Cold air getting in at the frame edge
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away
Rented homes near Polegate station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Which colour the sealant will be
- What guarantee comes with the work
- What insurance they hold
- Is VAT in the price?
Window mastic in Hellingly: local notes
Historic houses like Horselunges Manor (about 0.6 miles west) are a reminder that the area around Hellingly has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Hawkes Farm Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Historic houses such as Horselunges Manor, about 0.6 miles west, show how far back building around Hellingly goes, and older homes nearby need a sealant that suits their walls.

Questions from Hellingly
Can you do window mastic in Hellingly?
Yes, Hellingly is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Hellingly?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
