Wentworth: your questions answered
Is Wentworth in your area for window mastic?
Yes, Wentworth is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.
Do you cover smaller places like Wentworth?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Do you guarantee window mastic?
Yes. Every job comes with our one-year guarantee, and we’re fully insured.
How many windows can you do in a day?
Allow anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Windows and doors in Wentworth
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Botleys Mansion (about 3.1 miles south-east) nearby, there’s older building stock in the area around Wentworth as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Christ Church CofE Aided Infant School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Christ Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Longcross station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What else we do in Wentworth
Landlord and commercial work in Wentworth

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Do not aim a pressure washer at the joints
- Repaint timber before it’s bare
- Make sure the drainage slots are not blocked
- Walk round the house once a year and look at the joints
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
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. Catching it early keeps the fix to a reseal.
Why it’s worth doing now in Wentworth
The work is quick compared with the damage it prevents: the visit 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. Around Wentworth, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Wentworth, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Advice
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Different surfaces, different methods
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
What sealant work cannot fix
Before booking, it’s worth knowing the limits:
- Damp coming through the wall itself rather than the frame joint
- A sash or casement that won’t close properly
- Condensation trapped between the panes
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
