What window mastic looks like in Hambrook
Hambrook is close to 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 Warblington Castle (about 3.8 miles west) are a reminder that the area around Hambrook has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Nutbourne station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Chidham Parochial Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Wilfrid's Church and Hall, the joint between an old wall and a newer frame is normally the first place rain gets in.
Hambrook is about 5 miles west of Chichester, in West Sussex.

Window mastic in Hambrook
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you have mastic that’s falling out in pieces and water coming in at the bottom corners of a door, we can put it right, on uPVC windows, aluminium frames and patio & French doors alike.
In a village or hamlet like Hambrook, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job is covered by our 12-month guarantee, wherever you are in West Sussex.

Quotes for window mastic in Hambrook
Your quote is based on your job. We take into account:
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- Whether there’s mould to deal with
- The number and length of the joints
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
You do not need to know the technical terms. Just tell us:
- The address or postcode of the job
- Any access issues, like height or stairs
- A few pictures by email, if you can
- What’s wrong with the joints now
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Don’t aim a pressure washer at the joints
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
- Check the mastic once a year
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Rotten timber, which needs a joiner first
- Penetrating damp from a failed cavity tray or render
- Faulty window hardware
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Patio & French doors
- uPVC windows
- Timber windows & doors
- Window sills
- Composite doors
- Aluminium frames
How the job changes by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.

Why act early in Hambrook
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a small place like Hambrook, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why book with us
- Colour agreed with you before any work starts
- Quality sealants from Arbo and Everbuild
- A 12-month guarantee on all work
- 4.9 on Google from 180+ five-star reviews
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Your questions about window mastic in Hambrook
Do you work for landlords with property near Nutbourne station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Does the coastal weather in Hambrook affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Are you insured?
Yes. We’re fully insured.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
