Hartley Wespall Window Mastic
Problem with your window and door frames in Hartley Wespall? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Gaps between the frame and the inside reveal
- Rain getting in at the frame or under the sill
- White mastic on grey or black frames
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. 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.
Window mastic in Hartley Wespall
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for cold air getting in at the frame edge and untidy mastic left by window fitters, on uPVC windows, composite doors and timber windows & doors.
Homes in small places like Hartley Wespall often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

What we are called out for in Hartley Wespall
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Most people get in touch when they notice something like this:
- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
- Gaps between the frame and the inside reveal
For landlords with property near Bramley (Hants) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What to look for in a quote
- How the colour is chosen
- Whether they seal over old material or remove it

- Is VAT in the price?
Why act early in Hartley Wespall
Resealing frames is a short job: it takes most of a day for a typical house, less for a few frames. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Hartley Wespall, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Hartley Wespall, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Advice
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Air rooms to keep condensation down around windows
- Do not aim a pressure washer at the joints
- Do not paint over the silicone
- Keep timber frames painted
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What affects the cost of window mastic
Your quote is based on your job. We look at:
- The type of sealant required
- How many areas need sealing
- Access and height
- Mould in or behind the old joints
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Asking for a quote
When you call or email, these details help:
- What’s wrong with the joints now
- Whether it has been sealed before
- Roughly how big the job is
- Whether it’s a home or a business
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Honest limits
Before booking, it’s worth knowing the limits:
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

What window mastic looks like in Hartley Wespall
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Stratfield Saye House (about 2.3 miles north) are a reminder that the area around Hartley Wespall has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you look after a building such as Sherfield School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Mary the Blessed Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
