Window mastic in Strettington
Homes in Strettington have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on timber windows & doors, aluminium frames and window sills, and people most often call us about hard, cracked sealant around windows and mastic that’s falling out in pieces.
Homes in small places like Strettington often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job.

FAQs for Strettington
Do you work for landlords with property near Chichester station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Will you come out to Strettington?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
What does window mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
What information do you need?
Let us know what needs doing and where. If we need more, we will ask.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Strettington 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.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Ventilate rooms so frames don’t stay wet inside
- Look round the frames every year or so
- Keep paint off silicone joints
- Keep timber frames painted
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just phone 0345 464 0079 or send us an email.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What window mastic looks like in Strettington
Historic houses like Goodwood House (about 0.9 miles north-west) are a reminder that the area around Strettington 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. 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.
Rented homes near Chichester station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Boxgrove CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to St Andrew's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
