Window mastic for homes and businesses in Walton-on-the-Naze
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include gaps between the frame and the inside reveal and hard, cracked sealant around windows, across aluminium frames, patio & French doors and window sills.
In a smaller place like Walton-on-the-Naze, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
All of our work is guaranteed for twelve months.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Wash the frames with mild soapy water
- Walk round the house once a year and look at the joints
- Ventilate rooms so frames do not stay wet inside
- Do not use solvent cleaners on the joint
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What happens if it’s left?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. In an older home around Walton-on-the-Naze, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- How many rooms, windows or areas are involved
- How much there is to do
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
When you contact us, 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’s easy
- Any previous sealing or DIY work
We don’t publish a price list. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Soft or decayed wood in the frame
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

How the visit works
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. In a smaller place like Walton-on-the-Naze, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Walton-on-the-Naze: your questions answered
Do you work for landlords with property near Walton-On-The-Naze station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Will you come out to Walton-on-the-Naze?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.

What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
Frames and glazing around Walton-on-the-Naze
Walton-on-the-Naze is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Thorpe Hall (about 4.2 miles west) are a reminder that the area around Walton-on-the-Naze 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’s traditional sand mastic.
Managing a site like Walton on the Naze Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Walton-On-The-Naze station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
