Window mastic in Broad Oak, done properly
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you’re dealing with white mastic on grey or black frames and leaking joints at the ends of sills, we can put it right.
Around Broad Oak, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our 12-month guarantee in Broad Oak and across Hampshire.

What affects the quote in Broad Oak
We do not publish a price list. What we look at:
- The number of rooms or windows
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- Roughly how big the job is
- The address or postcode of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or drop us an email.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What we do, step by step
We keep the work tidy and contained to the joints we are treating. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. For a village or hamlet like Broad Oak, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
Getting a quote
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.

Common problems we fix in Broad Oak
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Most people get in touch after spotting one of these:
- Mastic that has split away from the wall
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
For landlords with property near Winchfield station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Faulty window hardware
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame

Windows and doors in Broad Oak
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as All Saints Church, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Mayhill Junior School, the mastic around its windows and doors needs looking after like any other building’s.

Why act early in Broad Oak
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Around Broad Oak, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Different surfaces, different methods
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
