What window mastic looks like in Hurst Wickham
With historic houses such as Ockenden Manor (about 5 miles north) nearby, there’s older building stock in the area around Hurst Wickham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Managing a site like St Lawrence CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St George include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic for homes and businesses in Hurst Wickham
The mastic around a window or door seals the gap between the frame and the wall. 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. Common call-outs are for gaps between the frame and the inside reveal and sealant in the wrong colour for the frame, on timber windows & doors, patio & French doors and window sills.
Mastic can only go onto a dry, clean joint, so window work in Hurst Wickham is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Your questions about window mastic in Hurst Wickham
Is Hurst Wickham in your area for window mastic?
Yes. We work across London and the South East, and Hurst Wickham is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is Hurst Wickham within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you get sealant to suit coloured frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we’ll match it as closely as we can.
Can I paint over the new sealant?
Not usually, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What affects the quote in Hurst Wickham
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Whether the work is at height
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Any access issues, like height or stairs
- Where the job is, and your postcode
We do not publish a price list. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or drop us an email.
What we do, step by step
On the day, we start by going over the job with you. Surfaces next to the work are protected before we start. The work usually takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Hurst Wickham needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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 parking rules near the property
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on

What else we do in Hurst Wickham
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Keep paint and stain on wooden frames in good order
- Check the mastic once a year
- Keep paint off silicone joints
- Air rooms to keep condensation down around windows
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Honest limits
To be straight with you, some problems need a different trade:
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal
- Aluminium frames
- Window sills
- Patio & French doors
- uPVC windows
- Timber windows & doors
- Composite doors
What we’re called out for in Hurst Wickham
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
The problems people usually mention when they call include:
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
If you let a flat or house near Hassocks station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Are they insured?
- How long to leave it before use
- How the joint is cleaned and prepared
