Window mastic for homes and businesses in Palmarsh
Homes in Palmarsh have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have untidy mastic left by window fitters and black, perished sealant on frames, we can help, whatever the surface.
Around Palmarsh, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
All our work comes with our 12-month guarantee, wherever you are in Kent.

How we quote for window mastic
Your quote is based on your job. We look at:
- The number and length of the joints
- Whether the work is at height
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
What we need to know
When you contact us, these details help:
- The problem you’ve noticed
- The rough size of the job
- Where the job is, and your postcode
- A few photos by email, if you can
There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, phone 0345 464 0079 or drop us an email.
Questions from Palmarsh
I let a flat near Sandling station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Does the coastal weather in Palmarsh affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Is the new sealant paintable?
Most silicone cannot be painted. Let us know beforehand, and we will use a paintable product where it suits.
How do I get a quote for window mastic in Palmarsh?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or email us and tell us what needs doing and where.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Around Palmarsh, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

Palmarsh homes and the weather
Palmarsh is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Westenhanger Castle (about 2.3 miles north) are a reminder that the area around Palmarsh has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Sandling station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Holy Cross, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Palmarsh Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Keeping the joints in good condition
Looking after new joints is easy:
- Air rooms to keep condensation down around windows
- Keep drainage slots and sill grooves clear
- Do not aim a pressure washer at the joints
- Paint up to the joint, not over it
Silicone cannot generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
How the visit works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from an hour or two to a full day, depending on how many frames there are. A visit to Palmarsh is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children

How the job changes by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Landlord and commercial work in Palmarsh
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
