Construction mastic in Romford, done properly
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on cladding and panel joints, floor and skirting junctions and window and door perimeters, and what we are called in for most is sanitary sealant damaged by following trades and frame gaps too wide for sealant alone. Facilities teams, main contractors and managing agents in Romford tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in a London area such as Romford means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What the job involves on each surface
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it.
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.
For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Questions we’re asked in Romford
Can work at a site such as Barking and Dagenham College fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you work in a London building with booked loading and goods-lift slots?
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.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you offer coloured sealant?
That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the 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.
Do you install fire-rated sealant as part of a package?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. Fire-stopping design and sign-off sit with the designer and building control.

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Get the mastic subcontractor involved early in the programme
- Bring the mastic contractor in after the last trades are through
- Check frame gaps are within the sealant’s range before sealing
- Brief following trades on areas that have been sealed
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault which is why protection after sealing matters.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.
Why it’s worth doing now in Romford
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification rather than at the snagging stage. Called in at the end, the same issues surface during handover. In Romford, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

- Workmanship guaranteed for 12 months
- Coloured sealants to suit the setting, where available

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected
- Send your site hours and access windows

General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

As part of Greater London, Romford is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in.
When a school such as Concordia Academy is extended or refurbished, the mastic package is often squeezed into the holidays.
