Poling questions
Will you come out to Poling?
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.
Does the coastal weather in Poling affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
What does window mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can new sealant go over the old?
No, it will not 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.
Window mastic in Poling, done properly
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on patio & French doors, window sills and timber windows & doors, and people most often call us about gaps where the sill meets the wall and cold air getting in at the frame edge.
Somewhere as small as Poling, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

What affects the cost of window mastic
Your quote is based on your job. We take into account:
- How many areas need sealing
- The old material and how stubborn it is
- The size of the job
- The type of sealant required
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- The rough size of the job
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.
Landlord and commercial work in Poling
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
If you manage several properties in or around Poling, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It normally takes a few hours for a handful of frames, longer for a whole house. In a small place like Poling, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Mention any tricky access

Advice
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Repaint timber before it’s bare
- Check the mastic once a year
- Avoid harsh chemicals near the mastic
- Don’t paint over the silicone
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What window mastic looks like in Poling
Poling is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Arundel station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like The Littlehampton Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.

Why act early in Poling
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 Poling, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Do you need window mastic in Poling?
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That is what backing rod is for.
Any of these means the joints need attention:
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Rushed sealant from a window installation
- Draughty joints inside around the window
If you live in an older home near The Parish Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
