Window mastic in Nettlestead Green: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Old Soar Manor (about 4.3 miles north-west) nearby, there’s older building stock in the area around Nettlestead Green as well as newer homes. 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.
Homes close to St Mary's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

About our window mastic in Nettlestead Green
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, call 0345 464 0079 or drop us an email with the number of frames and any access details. We’re often asked to deal with draughts coming in around windows and doors and untidy mastic left by window fitters, on aluminium frames, patio & French doors and window sills.
Homes in small places like Nettlestead Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What else we do in Nettlestead Green
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
For anyone letting property in or around Nettlestead Green, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
How we quote for window mastic
Your quote is based on your job. We take into account:
- The size of the job
- Whether there’s mould to deal with
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Asking for a quote
To make quoting easier, let us know:
- The address or postcode of the job
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, phone 0345 464 0079 or drop us an email.
Why deal with it now?
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Nettlestead Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

How the job changes by surface
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Signs you need window mastic in Nettlestead Green
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Common reasons people contact us include:
- Gaps between the frame and the inside reveal
- Mastic that is falling out in pieces
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
If you let a flat or house near Yalding station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are and we leave things clean and tidy. In a small place like Nettlestead Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on
