Windows and doors in Dogmersfield
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Farnham Castle (about 4.7 miles south-east) are a reminder that the area around Dogmersfield has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Dogmersfield Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as All Saints' Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Winchfield station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How we handle window mastic in Dogmersfield
A cold draught around a closed window often comes from the frame edge. 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’ll say so. We work on composite doors, aluminium frames and uPVC windows, and common reasons people get in touch are leaking joints at the ends of sills and water coming in at the bottom corners of a door.
Around Dogmersfield, 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.
There’s a 12-month guarantee on every job, whatever its size.

Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Dogmersfield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are.

Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Look round the frames every year or so
- Ventilate rooms so frames do not stay wet inside
- Keep timber frames painted
- Use gentle cleaners on frames and sealant
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
When something else is needed
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Penetrating damp from a failed cavity tray or render
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Faulty window hardware
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Should I try it myself first?
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. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Dogmersfield: your questions answered
Can you help a landlord with a rental near Winchfield station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Do you cover smaller places like Dogmersfield?
Yes, Dogmersfield is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What does window mastic cost?
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 will talk you through it.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
How long will my window job take?
Allow most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
How the job changes by surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- Roughly how big the job is
- Whether it’s a home or a business
- Pictures of the joints, sent by email
