How we handle construction mastic in Parsons Green
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers with projects in Parsons Green, sealing plot by plot or floor by floor as areas are released. The enquiries we see most involve failed sealant in an existing building being refurbished and inconsistent sealant finishes from plot to plot, across cladding and panel joints, sanitary and kitchen joints and window and door perimeters. For commercial sealant work in Parsons Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.
A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we’ll come back to it.

Site staff or a sealant specialist?
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.
Redoing a failed joint normally 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.
Do you need construction mastic in Parsons Green?
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, so they end up back on the snag list.
Most enquiries start with something like this:
- Sanitary sealant damaged by following trades
- Snag items on joints that need redoing before handover
- Oversized or tapered gaps around new frames
- Missed perimeter joints on a new elevation
Units on estates such as Hurlingham Business Park, 0.5 miles to the south of Parsons Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Before you book anyone
- What level of public liability insurance do they hold?
- How they’ll work around occupants
- Will failed sealant be removed rather than covered?
- Whether primer will be used where the manufacturer specifies it
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Phasing around occupants
- The size and state of each joint
- How accessible the joints are
- Whether old sealant has to be cut out first
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- Where the site is, with the postcode
- Whether the building will be occupied during the work
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

FAQs: Parsons Green
Could you schedule work at a campus like BIMM University for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on work at healthcare sites like Chelsea and Westminster Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can you work plot by plot or floor by floor?
The programme sets the job. Tell us the sequence and we’ll plan applicators around it so sealing follows the trades.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you work to our specification?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
Why it’s worth doing now in Parsons Green
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go. We can run snagging as its own phase before handover. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
Pricing mastic packages depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.

- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- We close out snagging and hand over with a 12-month guarantee.
