Window mastic in South Godstone
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. If you have mastic that has split away from the wall and rain getting in at the frame or under the sill, we can put it right, on window sills, patio & French doors and aluminium frames alike.
Around South Godstone, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

FAQs for South Godstone
Can you help a landlord with a rental near Godstone station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover South Godstone for window mastic?
Yes, South Godstone is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
Can you seal the gap between the frame and the plaster indoors?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
How much does window mastic cost in South Godstone?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.

How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
What we are called out for in South Godstone
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
Most people get in touch when they notice one of these:
- Hard, cracked sealant around windows
- Draughty joints inside around the window
- Gaps left after new windows were fitted
- A bead that does not match the frame
Rented homes near Godstone station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Comparing quotes

Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around South Godstone can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What you get with us
- White, clear, grey or another colour, product permitting
- Fully insured
- Any old sealant cut out fully, not covered over
- Neat joints and a tidy finish

What affects the cost of window mastic
Every job gets its own quote. This is what makes a difference:
- The amount of work
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- Whether there’s mould to deal with
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:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- Where the property is
- The type of property
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
Aftercare tips
A little care helps the new joints last. Our advice:
- Wipe condensation off the frames
- Keep paint off silicone joints
- Make sure the drainage slots aren’t blocked
- Keep paint and stain on wooden frames in good order
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the size of the job. Somewhere like South Godstone 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.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

Frames and glazing around South Godstone
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Titsey Place (about 4.9 miles north-east) are a reminder that the area around South Godstone has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around St Stephen, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as St Stephen's CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.
