Construction mastic near Putney
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Why act early in Putney
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. We can run snagging as its own phase before handover. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
We don’t publish prices, since every building and every scope is different. Call for a quote.
What you get with us
- 12 months’ guarantee on every job
- Our applicators hold CSCS cards
- Colour options checked against the specified product
- Failed material removed, not covered up

Construction mastic in Putney
Mastic Doctor has been a subcontractor on construction projects for over 20 years. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Putney, send drawings through our quote form, or phone or email us to talk it through. The enquiries we see most involve old sealant on a refurbishment that needs stripping before new work and window and door perimeters that won’t pass inspection, across sanitary and kitchen joints, internal decorators’ caulk and floor and skirting junctions. Whether you call it commercial sealant work, mastic application or joint sealing, in Putney it comes down to the same thing: the right product in a properly prepared joint.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Putney must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

How the job changes by surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.
On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Planning a London job such as one in Putney starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- 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.
Before we start on site
- Send your site hours and access windows
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Quoting for work in Putney
Each job is priced on its own details. The main factors are:
- Any access equipment needed
- Backing rod, priming and other preparation
- The product specified
- Location, for remote and island sites
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
What we need to price the job
We can often quote from photos and a few details. Please tell us:
- When you need the work done
- The product your specification calls for
- Whether an asbestos survey exists
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Construction mastic in Putney: the local picture
There are plenty of hotels within about 2 miles of Putney. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Site traffic in Putney falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Further education sites such as South Thames College Wandsworth Campus (to the east of Putney) are extended and refurbished from time to time, with mastic often programmed into the summer break. Work at a hotel such as Putney Hotel, under half a mile to the east of Putney, tends to be programmed around bookings, mastic included.
Putney is about 1 mile south-west of Fulham, in Greater London. Any commercial site in Putney is covered, for single jobs and planned programmes alike. Putney is one of 764 places we cover in Greater London for mastic packages. London is covered too, around 6 miles from Putney.
Anyone looking for construction mastic in SW15, SW19 and SW13 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

What we are called out for in Putney
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond, so preparation matters as much here as on a reseal.
These are often picked up first by site or facilities staff:
- Different trades sealing to different standards
- Internal caulk splitting as the building dries out
- Existing joints on a refurb that need cutting out and resealing
- Oversized or tapered gaps around new frames
On a campus such as University of Roehampton, 1 mile south-west of Putney, new teaching buildings and residences are usually built and refurbished around the academic year.

Common questions from Putney clients
Is hospital work, at somewhere like Royal Hospital for Neuro-Disability, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does your area include sites such as Hurlingham Business Park, near Putney?
Yes, sites like Hurlingham Business Park are within our area, along with the rest of Putney. Send details of the unit and the work through our quote form for a quick quote.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will you stick to the specified products?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can the building stay open while you work?
In the majority of cases, yes. We phase the work so most of the building stays in use.

When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Rework caused by others damaging completed areas
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
If in doubt, call 01277 525 020 or send photos by email and we will say what we think.
What we seal
- Window and door perimeters
- Brick and block movement joints
- Internal decorators’ caulk
- Cladding and panel joints
- Floor and skirting junctions
- Sanitary and kitchen joints
