DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Window mastic for homes and businesses in Durley
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We’re often asked to deal with hard, cracked sealant around windows and leaking joints at the ends of sills, across patio & French doors, uPVC windows and aluminium frames.
Around Durley, 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.
Big or small, you get the same 12-month guarantee in Durley and across Hampshire.

Durley homes and the weather
Historic houses like South Stoneham House (about 5 miles west) are a reminder that the area around Durley has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Hedge End station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Durley Church of England Controlled Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Air rooms to keep condensation down around windows
- Keep paint and stain on wooden frames in good order
- Make sure the drainage slots aren’t blocked
- Walk round the house once a year and look at the joints
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

FAQs for Durley
Do you cover smaller places like Durley?
Yes. Durley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Durley in your area for window mastic?
Yes. Our work covers London and the South East, and Durley is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How do I get a quote for window mastic in Durley?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What information do you need?
A short description and the location, with photos by email if possible. If we need more, we will ask.
The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Durley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

Advice
What we cannot put right
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
- Damp coming through the wall itself rather than the frame joint
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.
Where we work in Durley
- Patio & French doors
- uPVC windows
- Composite doors
- Window sills
- Timber windows & doors
- Aluminium frames
Common problems we fix in Durley
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
If you can see any of these, it’s time to have the joints looked at:
- Untidy mastic left by window fitters
- Cracked internal joints between frame and plaster
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
If you live in an older home near Church of the Holy Cross, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- Are they insured?
- Who turns up on the day
- How the surfaces are prepared before sealing
- What product goes in the joint
How the job changes by surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. We use a neutral-cure product.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
