- Old mastic that has gone black or come away
How the job changes by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
How we handle window mastic in Goldsworth Park
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on timber windows & doors, window sills and composite doors, and people most often call us about cracked sealant at the sill ends and sealant in the wrong colour for the frame.
Around Goldsworth Park, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
Every job is covered by a 12-month guarantee, wherever you are in Surrey.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep paint off silicone joints
- Don’t aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
- Walk round the house once a year and look at the joints
Silicone cannot normally be painted, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Goldsworth Park: your questions answered
I let a flat near Woking station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Goldsworth Park for window mastic?
Yes. Our work covers London and the South East, and Goldsworth Park is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Can I paint over the new sealant?
Most silicone cannot be painted. Let us know beforehand, and we will use a paintable product where it suits.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do you guarantee window mastic?
Yes. Our 12-month guarantee covers every job, inside or out.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
What affects the quote in Goldsworth Park
The price is agreed before any work begins. It’s based on:
- The number and length of the joints
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
When you call or email, these details help:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Window mastic in Goldsworth Park: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Botleys Mansion (about 4.4 miles north-east) are a reminder that the area around Goldsworth Park 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’s traditional sand mastic.
In the older streets around Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Woking station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

When to call us in Goldsworth Park
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Look out for any of the following:
- Rain getting in at the frame or under the sill
- A bead that does not match the frame
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
Schools such as Goldsworth Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like Goldsworth Park, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Tell us if parking is tricky
