Window mastic for homes and businesses in Old Town
Homes in Old Town have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for mastic that has split away from the wall and water coming in at the bottom corners of a door, across uPVC windows, window sills and timber windows & doors.
Homes around Old Town range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Whatever the size of the job, you get the same 12-month guarantee.

What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a morning for a couple of windows and a door. Parking around Old Town is generally 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.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Related advice
Do you need window mastic in Old Town?
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The problems people generally mention when they call are:
- Damp patches on the reveal after heavy rain
- Mastic that has split away from the wall
- Untidy mastic left by window fitters
- Whistling draughts around closed windows
Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Old Town: your questions answered
Is window mastic in a coastal place like Old Town any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Do you work for landlords with property near Eastbourne station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Is the new sealant paintable?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
How long does it take to reseal the windows on a house?
A handful of frames is a short visit. We confirm the timing with your quote.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.

Frames and glazing around Old Town
Old Town is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Eastbourne station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Old Town, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

How to look after the new joints
After the cure time, these simple habits help:
- Keep paint off silicone joints
- Keep solvents and bleach off the sealant
- Clear any debris from frame drain holes
- Walk round the house once a year and look at the joints
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
Composite doors
A composite door usually sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
