About our facade sealing in Parsons Green
We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you are dealing with old perimeter mastic that has dried out and previous reseals run over old sealant, we can put it right, whatever the surface. Searching for sealant specialists in Parsons Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. 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.
Every job we finish is backed by a 12-month workmanship guarantee, in Parsons Green as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. In Parsons Green, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with photos, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Preparing the site
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000
- Tell us which areas need to stay in use

How the job changes by surface
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint rather than the system it surrounds.
Building owners, agents and FMs in Parsons Green
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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. That’s why many clients bring in a specialist from the beginning.

What else we do in Parsons Green
Aftercare for building managers
To get the most from the new sealant:
- Check that rainwater leaves the facade the way it was designed to
- Brief window cleaners about newly sealed joints
- Inspect facade joints on a regular cycle
- Ask about asbestos in pre-2000 mastic
Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.

Quoting for work in Parsons Green
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Phasing around occupants
- Induction, permit and paperwork requirements
- The total length or number of joints

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Good information means a firmer quote. Helpful details to send:
- Asbestos survey details if the building is older
