Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Window mastic for homes and businesses in Ottershaw
From a single sill to a whole house of windows, you will get a clear quote before we start. To get one, call 0345 464 0079 or send us an email with the number of frames and any access details. Common call-outs are for hard, cracked sealant around windows and gaps between the frame and the inside reveal, on patio & French doors, aluminium frames and timber windows & doors.
Houses in smaller places like Ottershaw can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
We stand behind the work with a 12-month guarantee.

Your questions about window mastic in Ottershaw
I let a flat near Chertsey station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Do you cover Ottershaw for window mastic?
Yes, Ottershaw is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
Is the new sealant paintable?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.
Do you have sealant for grey or black windows?
Usually, yes. Mention the frame colour when you ask for a quote and we will use the nearest match.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
- Clean frames with a soft cloth and soapy water
- Air rooms to keep condensation down around windows
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What sealant work can’t fix
It helps to know what we cannot do too:
- Penetrating damp from a failed cavity tray or render
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Timber windows & doors
- Composite doors
- Patio & French doors
- uPVC windows
- Aluminium frames
- Window sills
Why deal with it now?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Ottershaw, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

It normally takes a few hours for a handful of frames, longer for a whole house. A visit to Ottershaw is planned like any other: the time, the access and where to park are agreed in advance.

Advice
Ottershaw homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Botleys Mansion (about 0.8 miles north) are a reminder that the area around Ottershaw 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.
In the older streets around Christ Church, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Ottershaw Christchurch Church of England Junior School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Chertsey station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
