Mastic sealing in Molesey, done properly
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms, and what we’re called in for most is the same joint failures repeated across a portfolio and movement joints with sealant missing. For commercial sealant work in Molesey, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Places the size of Molesey usually have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the job changes by surface
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Commercial and mixed-use buildings
Commercial occupiers usually stay open during the work so the work is phased.
Blocks and managed buildings in Molesey
Molesey sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 13 miles from Molesey. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Property owners at sites such as North Weylands Industrial Estate (1.8 miles south-west of Molesey) can have mastic renewed between lettings. If you’re responsible for a building such as Church of St Mary, frame and door mastic needs the same attention as any other property.
Molesey is about 6 miles west of Wimbledon, in Surrey. Our applicators travel to Molesey for work on mastic joints. Across Surrey, 379 places are covered, including Molesey. We also cover London, some 13 miles away.
We take on mastic joints across the KT8, KT7 and KT10 postcode area. For a building on Bell Road, Park Road and Kent Road or nearby, we can quote for mastic joints. Molesey sits on or close to the A309, which helps when planning parking and deliveries for the job. If your building is just outside Molesey, we cover Weston Green (1 mile south-east), Thames Ditton (1 mile south-east), Lower Green (1 mile south-west), Hinchley Wood (1 mile south-east) and Long Ditton (2 miles east). A short drive away, we cover Guildford (14 miles south-west), Woking (11 miles south-west), Epsom (5 miles south-east), Redhill (13 miles south-east), Ewell (5 miles south-east) and Egham (9 miles west).
Landmarks near Molesey
In Molesey, that means premises near The Albion pub, Cigarette Island Park and Esher College and the streets around them. The nearest railway station is Hampton Court station, roughly 0.7 miles north-east of the centre. Nearby you will also find Teddington Memorial Hospital (2.2 miles north) and Bentall Centre (2.4 miles north-east). Not far away are The Lake and The Wood.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Check sealant joints during planned building inspections
- Start inspections with the most exposed faces
- Have the asbestos survey to hand for older buildings
- Encourage occupiers to report problems at frames
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Questions we are asked in Molesey
Is Molesey too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
We manage a building near Hampton Court station. Can you help?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
How long does a job like this take?
It depends on the scope, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Signs you need mastic sealing in Molesey
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Clients normally get in touch after noticing something like this:
- Cracked, hardened mastic round windows on a block
- Patchy repairs in mismatched sealant
- Estate-wide sealant that is simply worn out
- Water getting in round frames after rain
Site managers at schools like The Orchard Infant School can fit frame mastic into the summer works.
Before you book anyone
- Will failed sealant be removed rather than covered?
- Who will actually carry out the work
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Several jobs near Molesey can be grouped on one trip. Tell us your site hours and we will plan around them.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Tell us which areas need to stay in use
- Tell staff and tenants when we will be in
- Confirm the product named in the specification
