About our mastic sealing in Chertsey
Managing agents and housing associations typically need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you have water getting in round frames after rain and movement joints with sealant missing, we can help, on shopfronts below residential blocks, communal kitchens and washrooms and balcony and threshold joints alike. A single leaking joint is often how a building in Chertsey first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In a smaller place such as Chertsey, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Plan resealing building by building rather than complaint by complaint
- Keep bins and bikes away from communal door frames
- Keep a record of when each building was resealed
- Start inspections with the most exposed faces
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
Looking after buildings in and around Chertsey
The 2 miles around Chertsey include four care or nursing homes. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. Rainfall across the South East, Chertsey included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
If you look after a block within reach of Chertsey station (less than half a mile west of Chertsey), frame and balcony mastic can be renewed on one programme. Site managers at schools like St Anne's Catholic Primary School can fit frame mastic into the summer works.
Chertsey is about 6 miles north-east of Woking, in Surrey. Our applicators travel to Chertsey for work on mastic joints. Chertsey is one of 379 places we cover in Surrey for mastic joints. For work in that direction, see our London page, about 19 miles away.
Commercial sites across KT16 and KT15 are covered for mastic joints. If your site is on Station Road, Charles Street and King Street or close by, we can quote for mastic joints. Being close to the A317 and A320, Chertsey is easy to get to with materials and equipment. Nearby places we also cover include Lyne (1 mile west), Row Town (2 miles south), Ottershaw (2 miles south-west), Trumps Green (3 miles west) and Stonehill (3 miles south-west) for mastic joints. Further afield, our area takes in Guildford (10 miles south), Woking (6 miles south-west), Camberley (10 miles west), Epsom (11 miles east), Ewell (11 miles east) and Egham (3 miles north-west).
Near you in Chertsey
We work on buildings around Chertsey High School, Sir William Perkins's School and Woburn Park, among other places. There’s a railway station in Chertsey itself: Chertsey station.

What we’re called out for in Chertsey
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.
What tends to prompt an enquiry:
- Damaged joints in communal entrances and corridors
- Leaks at window and door perimeters
- Complaints coming in block by block
- Brittle perimeter mastic across a building
If you manage student housing near a university such as Royal Holloway University (3.7 miles north-west of Chertsey), the summer turnaround is the time for mastic.
Before you book anyone
- Will failed sealant be removed rather than covered?
- How long is the guarantee, and what does it include?
- How the joint faces will be prepared and primed
- What site paperwork they can supply
Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Take a look at what affects the cost and our accreditations and insurance.
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Backing rod, priming and other preparation
- Phasing around occupants
- The product specified
- Whether old sealant has to be cut out first
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- The site address and postcode
- Drawings or a marked-up plan, if available
- A wide shot and a close-up of the area
- Any dates the work must fit around
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
Planned maintenance
Planned resealing replaces emergency callouts and spreads the work.
Your questions answered
Will you work in a care home in Chertsey without moving residents out?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
Will you take on a block within reach of Chertsey station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Chertsey in your area?
Yes. Chertsey is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, speak to us on 01277 525 020 or send details through our quote form.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so there are no surprises.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
