About our mastic sealing in Handcross
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 are a Constructionline member and CHAS accredited, and we carry public liability insurance. The enquiries we see most involve cracked, hardened mastic round windows on a block and communal area joints that look neglected, on communal kitchens and washrooms, shopfronts below residential blocks and communal entrances and stairwells. For commercial sealant work in Handcross, you deal with one contact from quote to sign-off, whether it’s one building or several.
In and around smaller places like Handcross, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Site staff or a sealant specialist?
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.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

How the job changes by surface
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
Tenement and older buildings
Older mastic can contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
Maintenance after handover
After handover, a little attention goes a long way:
- Prioritise elevations facing the weather
- Log resealing dates block by block
- Make it easy for occupiers to report draughts
- Make mastic part of routine maintenance checks
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
FAQs: Handcross
Can you quote for a block close to Balcombe station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Is Handcross off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.

Planned mastic for Handcross portfolios
Handcross sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 31 miles from central London, Handcross is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
If you’re responsible for a building such as All Saints, frame and door mastic needs the same attention as any other property. With historic buildings such as Tyes Place (1.9 miles south-east of Handcross) in the wider area, owners of older properties around Handcross should expect mastic to need a product that suits old masonry.

What affects the price in Handcross
Each job is priced on its own details. The things that drive the figure:
- Travel to remote or island sites
- Access and working height
- The size and state of each joint
- How much existing material needs removing
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
