Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. Site teams most often ask us about occupiers reporting cold air round windows and leaks at window and door perimeters, across window and door perimeters on blocks, shopfronts below residential blocks and external wall and movement joints. Most enquiries from Cross in Hand start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Why act early in Cross in Hand
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. For buildings around smaller places like Cross in Hand, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

FAQs: Cross in Hand

How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Frames, entrances and external joints in Cross in Hand
Central London is about 39 miles from Cross in Hand. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.
For agents with blocks near Buxted station (3.9 miles west of Cross in Hand), a block-wide mastic programme deals with frames, balconies and entrances in one go. If you own or manage units on a site such as Station Road Industrial Estate (1.5 miles east of Cross in Hand), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Common problems we fix in Cross in Hand
Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Look out for the following:
- Leaks at window and door perimeters
- No planned programme for sealant
- Window mastic that has split and shrunk
- Damaged joints in communal entrances and corridors
For a school such as Cross-in-Hand Church of England Primary School, perimeter mastic on windows and doors is a holiday job.
