How we handle mastic sealing in Sullington
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on balcony and threshold joints, communal kitchens and washrooms and shopfronts below residential blocks, and the usual reasons a site gets in touch are water getting in round frames after rain and window mastic that has split and shrunk.

Sullington: questions and answers
We manage a building near Amberley station. Can you help?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Is Rock Business Park, near Sullington, within your area?
Yes. We cover Sullington and the area around it, including industrial estates, business parks and retail parks such as Rock Business Park. Photos and a short description are enough for a first look.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Do you work in Sullington?
Yes. We take on work across Sullington.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
What happens if it’s left?
Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Halls, stores and units around places like Sullington may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Rural sites near Sullington may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

What else we do in Sullington
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Share the asbestos register when you send details
- Protect low-level joints in entrances
- Group repairs into a planned programme
- Share your contractor requirements early
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
