Tinsley Green homes and the weather
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.
In the older streets around St Michael and All Angels Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Forge Wood Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Tinsley Green is about 3 miles south of Horley, in West Sussex. Jobs in Tinsley Green get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee.

Window mastic in Tinsley Green
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. Typical jobs include draughty joints inside around the window and whistling draughts around closed windows, on aluminium frames, composite doors and patio & French doors.
Around Tinsley Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

How we quote for window mastic
Call for a quick quote. The main things that affect it are:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- How much there is to do
- Which sealant suits the joint
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
Helping us quote
To make quoting easier, let us know:
- The type of property
- Roughly how big the job is
- Where the job is, and your postcode
- Whether it has been sealed before
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or send us an email.
Leave it or put it right?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In a small place like Tinsley Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- ARBOMaster approved applicator
- We leave the area clean and tidy
- Any old sealant cut out fully, not covered over

Your questions about window mastic in Tinsley Green
Can you do window mastic in Tinsley Green?
Yes. Our work covers London and the South East, and Tinsley Green is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Do you cover smaller places like Tinsley Green?
Yes, Tinsley Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is the new sealant paintable?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
How long will my window job take?
The work takes a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
- Keep drainage slots and sill grooves clear
- Wash the frames with mild soapy water
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
When something else is needed
New sealant cannot fix everything, and we will tell you before we start. It will not solve:
- Rotten timber, which needs a joiner first
- Broken hinges, locks or handles
- A failed sealed unit that has misted up
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
Joints and surfaces we work on
- uPVC windows
- Timber windows & doors
- Aluminium frames
- Patio & French doors
- Composite doors
- Window sills
Signs you need window mastic in Tinsley Green
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Keep an eye out for any of the following:
- Whistling draughts around closed windows
- Gaps where the sill meets the wall
- Hard, cracked sealant around windows
- Water coming in at the bottom corners of a door
For landlords with property near Gatwick Airport station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What we do, step by step
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a morning for a couple of windows and a door.

Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- 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.
Before we arrive
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
