Building and refurbishing in St George's Fields
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in St George's Fields. Deliveries are booked and storage is tight, so mastic materials come in as needed. A 2-mile radius around St George's Fields takes in a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Units on estates such as Grand Vitesse Industrial Estate, under half a mile to the north of St George's Fields, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For a contractor at a hotel such as The Bridge Hotel, less than half a mile to the east of St George's Fields, the mastic often has to be finished before a reopening date.

How we handle construction mastic in St George's Fields
We work to the specification and the programme rather than whatever product is to hand. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. We work on internal decorators’ caulk, sanitary and kitchen joints and cladding and panel joints, and the failures we’re asked to look at most are external joints sealed in damp or cold conditions that are now failing and existing joints on a refurb that need cutting out and resealing. Most enquiries from St George's Fields 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.
Every London site, St George's Fields included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

General trades versus a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Building owners, agents and FMs in St George's Fields
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a job in St George's Fields, access comes first. Give us the hours we can be on site and we will schedule to suit.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.

Questions about St George's Fields
Do you take on jobs in St George's Fields where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Is Grand Vitesse Industrial Estate, near St George's Fields, within your area?
Yes. Estates, retail parks and business parks around St George's Fields, Grand Vitesse Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Can you come in just for snagging?
Yes. Damaged, missed or untidy joints are stripped and done again properly to suit the programme.
Will you stick to the specified products?
We work to the specification and the manufacturer’s installation guidance. Preparation, backing and depth follow the product guidance.
Do you offer coloured sealant?
It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
What happens if it’s left?
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference, especially externally. Where an alternative is genuinely suitable, we will say so. Getting scaffold, permits or access booked in St George's Fields takes effort, so it makes sense to deal with every failing joint while access is in place.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Why us?
- Colours chosen to suit frames, cladding or finishes where possible

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Approving fire stopping as compliant
- Oversized gaps that need packing or adjustment by others
- Faulty frames rather than failed sealant
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly.
Surfaces we seal
- Brick and block movement joints
- Floor and skirting junctions
- Sanitary and kitchen joints
- Cladding and panel joints
- Window and door perimeters
- Internal decorators’ caulk
Do you need construction mastic in St George's Fields?
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge. We flag them early rather than filling them with sealant that won’t last.
It’s worth sending us details if you spot any of the following:
- Missed perimeter joints on a new elevation
- Existing joints on a refurb that need cutting out and resealing
- A mastic package split between trades with no clear owner
- Caulk cracking where joints are moving more than expected
New wings at hospitals like Evelina London Children's Hospital, 0.6 miles to the west of St George's Fields, bring long runs of window and panel joints to seal.
What to look for in a quote

- How joint depth will be controlled
