Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Deciding which fire-stopping product a penetration needs
- Faulty frames rather than failed sealant
- Designing joint widths or choosing the specification (that sits with the designer)
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Construction mastic in South Bermondsey, done properly
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas. Sealing too early only means coming back once others have damaged it. If you have early adhesion failures on new external joints and frame perimeters left unsealed or poorly sealed, we can put it right. Looking for mastic applicators who cover South Bermondsey? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around South Bermondsey, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
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.
What happens if it’s left?
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Leave it late and they turn up on the snag list. In South Bermondsey, 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.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What you get with us
- Public liability insurance in place
- Health and safety: CHAS accredited
- Matching to RAL references, product permitting
- Work to your specification and the manufacturer’s guidance

Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in South Bermondsey. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.

New units and refits on sites such as Bermondsey Trading Estate (under half a mile north-east of South Bermondsey) need their panel and perimeter joints sealed to the specification. Work at a hotel such as Peckham Rooms Hotel (to the south of South Bermondsey) tends to be programmed around bookings, mastic included.

A quote for mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.

Surface by surface
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps so we will flag where the detail needs something different. Tell us what records you need and we will confirm with the quote.
Our process
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. All of Greater London is in the ULEZ, and kerbside space in South Bermondsey can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- 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.
Preparing the site
- For older buildings, check the asbestos register before work
- Share your working hours and any access restrictions
- Confirm the product named in the specification
Getting a fixed quote
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

FAQs: South Bermondsey
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough
Is hospital work, at somewhere like Guy's Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What do you charge?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

Yes. South Bermondsey falls within our area, and you can call the office on 01277 525 020 or send photos by email to get started.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
