Mastic sealing in Hempstead, done properly
Across Hempstead and the rest of Medway, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. We work on shopfronts below residential blocks, communal entrances and stairwells and window and door perimeters on blocks, and what we’re called in for most is occupiers reporting cold air round windows and water getting in round frames after rain.

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Have the asbestos survey to hand for older buildings
- Ask residents or tenants to report leaks and draughts early
- Log resealing dates block by block

Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
FAQs: Hempstead
Can you quote for a block close to Rainham (Kent) station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Can work in a care setting near Hempstead go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you work in Hempstead?
Yes. Hempstead falls within our area, and you can speak to us on 01277 525 020 or send details through our quote form to get started.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
What we are called out for in Hempstead
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.
Look out for the following:
- Cracked, hardened mastic round windows on a block
- Complaints coming in block by block
- Old repairs sealed over failed mastic
- Leaks at window and door perimeters
For agents with blocks near Rainham (Kent) station, 2.1 miles north-east of Hempstead, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Comparing quotes
- Whether old or failed sealant will be cut out, not overlaid
- Their approach to joint depth and backing
- Health and safety accreditation such as CHAS
- Can the work be phased to keep areas open?
Leave it or put it right?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why appoint us
- A range of standard colours, depending on the product
- Joints cleaned back to sound surfaces
- CSCS-carded applicators
- Colours chosen to suit frames, cladding or finishes where possible

When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes a few days for most blocks, with larger programmes scheduled building by building. If neighbouring businesses or buildings around Hempstead need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
