How we handle construction mastic in Richmond
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you have window and door perimeters that won’t pass inspection and bath and shower joints scraped during the final clean, we can put it right, on window and door perimeters, cladding and panel joints and sanitary and kitchen joints alike. Whoever orders the work in Richmond, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, give us a call on 01277 525 020 or send photos by email and we’ll arrange a return visit.

Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. In Richmond, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- 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 right away.
- Final snagging is completed and the 12-month guarantee applies.
Preparing the site
- Tell staff and tenants when we’ll be in
- Explain the parking and delivery arrangements
- Tell us which areas need to stay in use

Advice
What affects the price in Richmond
We price every job individually. The things that drive the figure:
- How much existing material needs removing
- The total length or number of joints
- How accessible the joints are
- The size and state of each joint
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Sending details for a quote
We can often quote from photographs and a few details. Please tell us:
- When you need the work done
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
- Photos of the joints, close up and from further back
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.
Questions about Richmond
Can work at a site such as University of London fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work to our specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Do you work in Richmond?
Yes. Sites across Richmond are covered, and the same phone number covers every area.
What happens if it’s left?
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Damage to finishes by other trades after we have sealed
- Frames fitted out of tolerance
If in doubt, phone 01277 525 020 or email us and we’ll say what we think.

- Floor and skirting junctions

For contractors refurbishing units at places like Ivybridge Retail Park, which lies west of Richmond, the mastic covers cladding panels, roller-door and window perimeters.
