Mastic sealing in Upper Wield, done properly
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on external wall and movement joints, balcony and threshold joints and window and door perimeters on blocks, and the usual reasons a site gets in touch are estate-wide sealant that is simply worn out and complaints coming in block by block. Most enquiries from Upper Wield start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
In and around smaller places like Upper Wield, 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.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
- Glazing that needs replacing
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Site staff or a sealant specialist?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Commercial clients in Upper Wield
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

What the job involves on each surface
Window and door perimeters on blocks
We typically work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we’ll plan around them.
Blocks and managed buildings in Upper Wield
Upper Wield is about 50 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Rainfall across the South East, Upper Wield included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
Churches, halls and community buildings such as Church of St James are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. With historic buildings such as Hall Place, 2.2 miles east of Upper Wield, in the wider area, owners of older properties around Upper Wield should expect mastic to need a product that suits old masonry. Property owners at sites such as Barton Industrial Estate (to the south of Upper Wield) can have mastic renewed between lettings.

Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. If others near Upper Wield need work, visits can be combined. A fixed quote is given before anything starts.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Preparing the site
- Make sure the joints can be reached
- Confirm the product named in the specification
- For older buildings, check the asbestos register before work

Advice
Upper Wield: questions and answers
Do you take on block-wide or estate-wide mastic work in Upper Wield?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Is Upper Wield too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Around Upper Wield, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
