Nork Window Mastic
Professional window mastic in and around Nork, with every bit of old sealant taken out first.
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
- Gaps left after new windows were fitted
Window mastic for homes and businesses in Nork
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on window sills, uPVC windows and aluminium frames, and common reasons people get in touch are cracked internal joints between frame and plaster and sealant in the wrong colour for the frame.
Around Nork, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
All our work is covered by our one-year guarantee, wherever you are in Surrey.

Leave it or put it right?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Nork, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we tell you how long to leave it before we go. For a job in Nork, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts

Advice
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Use gentle cleaners on frames and sealant
- Avoid harsh chemicals near the mastic
- Keep jet washers away from the mastic
- Paint up to the joint, not over it
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Frames and glazing around Nork
With historic houses such as Fitznells Manor (about 2.4 miles north-west) nearby, there’s older building stock in the area around Nork as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Warren Mead Infant School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in. Rented homes near Banstead station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

What else we do in Nork
Nork: your questions answered
Is Nork within the area you cover?
Yes. Nork is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Banstead station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do you have insurance?
Yes. We are fully insured.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Can resealing stop a draught around my window?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
What affects the cost of window mastic
We do not publish a price list. The quote depends on:
- The size of the job
- Working hours on commercial sites
- Whether there’s mould to deal with
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
When you call or email, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Photos by email, if that is easy
- If someone has resealed it before
We do not publish a price list, because every job is different. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or drop us an email.
What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
