Mastic sealing in Hamsey
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. If you have draughts at frames across a block and movement joints with sealant missing, we can help. A single leaking joint is often how a building in Hamsey 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.
Around smaller places like Hamsey, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Surface by surface
Tenement and older buildings
Natural stone can be marked by the wrong sealant, so we pick a grade that won’t mark it.
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. How each joint is reached is agreed at quote stage.
What happens if it’s left?
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. Around Hamsey, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What you get with us
- Colour agreed before work starts
- Matching to RAL references, product permitting
- Fully insured, including public liability cover
- Joints cleaned back to sound surfaces

Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Looking after buildings in and around Hamsey
Hamsey is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Hamsey lies roughly 42 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.
Older community buildings, The Parish Church of St Peter among them, often have frames of mixed ages whose mastic varies. For owners of several units at places like Malling Industrial Estate, 1.3 miles south-east of Hamsey, one programme can deal with frame and external mastic across the lot.

Related advice
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- List the paperwork your organisation requires when you send details
- Log resealing dates block by block
- Prioritise elevations facing the weather
- Keep bins and bikes away from communal door frames
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
