Window & door mastic in Weston, Southampton
Our applicators work in Weston on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a one-year guarantee.

- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
About our window mastic in Weston
Around Weston we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Common call-outs are for leaking joints at the ends of sills and water coming in at the bottom corners of a door, on aluminium frames, timber windows & doors and patio & French doors.
In a smaller place like Weston, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Big or small, it’s backed by our one-year guarantee in Weston and across Southampton.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Composite doors
Front doors take the weather head on. Those corners get the most care.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Look round the frames every year or so
- Keep paint off silicone joints
- Don’t aim a pressure washer at the joints
- Clean frames with a soft cloth and soapy water
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The amount of work
- Access and height
- Working hours on commercial sites
- Mould in or behind the old joints
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Pictures of the joints, sent by email
- The rough size of the job
- Any previous sealing or DIY work
- Where the job is, and your postcode
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or send us an email.
Landlord and commercial work in Weston
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a smaller place like Weston, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
What you get with us
- 20+ years of sealant experience
- Experience in homes, commercial sites and hotels
- Sealant colour chosen to suit
- Any old sealant cut out fully, not covered over

Weston homes and the weather
Weston is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Medieval Merchant's House (about 1.8 miles north-west) nearby, there’s older building stock in the area around Weston as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Weston Shore Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Sholing station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Holy Trinity Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

What happens on the day
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Parking around Weston is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, 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
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on

FAQs for Weston
Can you help a landlord with a rental near Sholing station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Does living near the coast affect window mastic in Weston?
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 remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months, inside or out.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
