DIY sealant or a professional job?
Some jobs are best left to a professional: 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.
Window mastic for homes and businesses in Jack's Hatch
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include leaking joints at the ends of sills and old mastic that has gone black or come away, across composite doors, timber windows & doors and uPVC windows.
Homes in small places like Jack's Hatch often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What else we do in Jack's Hatch
For landlords and businesses
Landlords and agents in Jack's Hatch can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- How easy the joints are to reach
- Any mould that needs treating
- The product the joint needs
- How many rooms, windows or areas are involved
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- The problem you’ve noticed
- The rough size of the job
- Pictures of the joints, sent by email
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Jack's Hatch, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts

Common questions in Jack's Hatch
I let a flat near Roydon station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Jack's Hatch?
Yes, Jack's Hatch is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can you match the sealant to my frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Is the new sealant paintable?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
When something else is needed
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
- Worn gaskets, brush seals or a door that has dropped
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Where we work in Jack's Hatch
- Composite doors
- Aluminium frames
- Timber windows & doors
- Window sills
- Patio & French doors
- uPVC windows
What window mastic looks like in Jack's Hatch
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Roydon station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Water Lane Primary Academy, the mastic around its windows and doors needs looking after like any other building’s.

Do you need window mastic in Jack's Hatch?
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Keep an eye out for these signs:
- A bead that doesn’t match the frame
- Cracked internal joints between frame and plaster
- Whistling draughts around closed windows
- Black, perished sealant on frames
For an older house near a landmark such as St James with St Luke, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- What preparation is included
- Who turns up on the day
- Is the old sealant removed completely?
- Whether you can choose the colour
Why it’s worth doing now in Jack's Hatch
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Around Jack's Hatch, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
