About our mastic sealing in Putney
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in Putney carry our 12-month guarantee. We work on window and door perimeters on blocks, shopfronts below residential blocks and balcony and threshold joints, and what we are called in for most is complaints coming in block by block and failed external movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Putney is the same: the right product in a properly prepared joint.
For managing agents in Putney, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Commercial clients in Putney
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Quoting for work in Putney
Before we quote, we look at:
- Whether the work must be split into stages
- Location, for remote and island sites
- Access and working height
- Removal of failed or old sealant
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- The postcode of the building
- Anything awkward about access or site hours
- Your programme or deadline
- Whether an asbestos survey exists
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Your questions answered
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
Will you take on work at estates like Hurlingham Business Park, close to Putney?
Yes. Our area takes in Putney and its surroundings, with estates and business parks such as Hurlingham Business Park included. Send details of the unit and the work through our quote form for a quick quote.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a quote.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can you reseal a whole block or estate?
Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Masonry that has broken away beside the joint
- Leaks through the frame itself rather than the perimeter
- Materials that need asbestos testing before work
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.
What we seal

What the job involves on each surface
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Before we start on site
- Arrange parking or a loading space
- Send your site hours and access windows
- Let building users know which areas are affected

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Block-wide mastic in Putney
London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We fit the programme to your notice periods.
Schools and community buildings such as Our Lady of Victories Catholic Primary School need frame and external mastic kept sound like any building. Blocks of flats and mixed-use buildings often cluster around stations such as Putney station (less than half a mile east of Putney) and their window and balcony mastic tends to age at the same rate across a building. If you’re responsible for a building such as Polish Church of St John the Evangelist, frame and door mastic needs the same attention as any other property.
Putney is about 1 mile south-west of Fulham, in Greater London. We cover Putney and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. 764 places across Greater London fall within our area, including Putney. Our London page has more on work in that area.
Commercial sites across SW15, SW19 and SW13 are covered. Streets here include Putney High Street, Upper Richmond Road and Spencer Walk. Access to Putney is via the A3 and B306. We also cover Roehampton (1 mile south-west), Barnes (1 mile north-west), Fulham (1 mile north-east), Mortlake (2 miles west) and Wimbledon Park (2 miles south) for mastic joints. Nearby towns on our patch include London (6 miles north-east), City of Westminster (5 miles north-east), Marylebone (5 miles north-east), Kensington (3 miles north), St Pancras (6 miles north-east) and Shoreditch (8 miles north-east).
Around Putney
In Putney, that means premises near Putney School of Art and Design, Bishops Park and The Railway pub and the streets around them. There’s a railway station in Putney itself: Putney station. Well-known places in the area include Putney Exchange (less than half a mile east) and Antique Breadboard Museum (under half a mile north-east). The countryside around Putney includes Henman Hill and Battersea Park Lake.
What happens if it’s left?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix when the frames themselves are sound. In Putney, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
