Do you need mastic sealing in Cripp's Corner?
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
It’s worth sending us details if you spot any of the following:
- Open joints in brickwork or panels
- Communal area joints that look neglected
- No planned programme for sealant
- Occupiers reporting cold air round windows
Landlords with units on estates such as Vinehall Business Centre (to the south-west of Cripp's Corner) can bring frame, door and external mastic across several units into one programme.

Mastic sealing in Cripp's Corner, done properly
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. The enquiries we see most involve failed external movement joints and no planned programme for sealant, on external wall and movement joints, communal entrances and stairwells and communal kitchens and washrooms. A single leaking joint is often how a building in Cripp's Corner first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Cripp's Corner, 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.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Common questions from Cripp's Corner clients
Is Cripp's Corner too small for you to travel to?
Not at all. Cripp's Corner is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Will you take on work at estates like Vinehall Business Centre, close to Cripp's Corner?
Yes. Our area takes in Cripp's Corner and its surroundings, with estates and business parks such as Vinehall Business Centre included. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we will confirm the approach in the quote.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Why it’s worth doing now in Cripp's Corner
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Converted and older buildings near places like Cripp's Corner tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
A quote for mastic joints depends on quantities, condition and access. Call for a quote.

After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Keep a record of when each building was resealed
- Look at the sunniest and most exposed elevations first
- Have the asbestos survey to hand for older buildings
- Share your contractor requirements early
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.
Planned mastic for Cripp's Corner portfolios
Cripp's Corner sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Cripp's Corner lies roughly 46 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Buildings close to stations like Robertsbridge station, 3 miles north-west of Cripp's Corner, are often flats over shops, with frame mastic to keep sound. Historic properties like Durhamford Manor (to the south of Cripp's Corner) show the age of some local stock, where frame mastic must suit soft brick or stone.
Cripp's Corner is about 7 miles north of Hastings, in East Sussex. Anywhere in TN32, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

How the quote is worked out
We price every job individually. The main factors are:
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
