Window & door mastic in Harbridge, Hampshire
Problem with your window and door frames in Harbridge? We cut out the old, prepare the joints and apply the right sealant.
- Sealant in the wrong colour for the frame
- Leaking joints at the ends of sills

Honest limits
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Rotten timber, which needs a joiner first
- Penetrating damp from a failed cavity tray or render
- A door that needs adjusting, rehanging or new seals
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Window mastic in Harbridge
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We work on timber windows & doors, uPVC windows and aluminium frames, and the jobs we see most are leaking joints at the ends of sills and cold air getting in at the frame edge.
Around Harbridge, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Questions from Harbridge
Can you do window mastic in Harbridge?
Yes. Our work covers London and the South East, and Harbridge is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
What guarantee comes with window mastic in Harbridge?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you work for landlords and businesses?
Yes, often. Several properties can go on one quote.
Do you take out the old sealant first?

Can new window sealant be painted?
Not generally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.

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.

Different surfaces, different methods
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.

What else we do in Harbridge
What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Older cottages and farmhouses around Harbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Look round the frames every year or so
- Repaint timber before it’s bare
- Clean frames with a soft cloth and soapy water
- Avoid harsh chemicals near the mastic
Most silicone sealants won’t take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Landlords, agents and businesses in Harbridge
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Harbridge, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Do you need window mastic in Harbridge?
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.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant at the sill ends
- Gaps between the frame and the inside reveal
- Whistling draughts around closed windows
- Cracked or shrunken mastic around the frame
Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
