Owners, agents and contractors
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Mastic sealing in Shoreditch
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on communal entrances and stairwells, window and door perimeters on blocks and shopfronts below residential blocks, and the failures we are asked to look at most are movement joints with sealant missing and draughts at frames across a block. Whether you call it commercial sealant work, mastic application or joint sealing, in Shoreditch it comes down to the same thing: the right product in a properly prepared joint.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we’ll come back to it.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, 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.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Why it’s worth doing now in Shoreditch
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Getting scaffold, permits or access booked in Shoreditch takes effort, so it makes sense to deal with every failing joint while access is in place.

Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a few days for most blocks, with larger programmes scheduled building by building. All of Greater London is in the ULEZ, and kerbside space in Shoreditch can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you
- Share the asbestos register for older buildings
- Let us know about inductions and permits
- Tell us which areas need to stay in use

What do you charge?

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.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Do you need mastic sealing in Shoreditch?
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Things that typically lead to an enquiry:
- Repeated reactive repairs to the same buildings
- Communal area joints that look neglected
- Patchy repairs in mismatched sealant
- Window mastic that has split and shrunk
If you own or manage units on a site such as Anchor Retail Park, 1.2 miles to the east of Shoreditch, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
