Commercial mastic work in Bexleyheath
Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Bexleyheath, the quickest start is to ring 01277 525 020 or email the details over with a list of addresses. If you’re dealing with gaps behind commercial kitchen worktops and sinks and hardened, chalky sealant on south-facing or exposed elevations, we can put it right. A specialist sealant contractor works differently from a general builder: in Bexleyheath, that means joint design, primers and backing rod as standard.
We price commercial jobs in Bexleyheath from photographs, drawings or a site visit, and the scope is set out in writing.
For managing agents and FMs looking after premises in Bexleyheath, access is usually the first question: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building owners, agents and FMs in Bexleyheath
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few hours to several days on most single sites, depending on joint lengths and access, and our waste is bagged and taken away as we go. In Bexleyheath, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Where parts of the building must stay open, the work is phased.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
Before we start on site
- Point out any areas we must not close
- For older buildings, check the asbestos register before work
- Tell us what induction or permit system the site runs
Ask for a quote
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.
Related advice
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Check sealant as part of routine building inspections
- Log reseals in the O&M or maintenance records
- Make sure ventilation in wet areas is switched on and working
- Ask cleaners to use a soft cloth and mild cleaner on sealant
Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early, especially on exposed elevations and in washrooms. Should something look amiss, you can call the office on 01277 525 020 or email a schedule or drawings and send a picture.
Sealant rarely fails all at once across a building. A few splits this year usually mean more next year. We can assess the lot and suggest what to do now and later.
When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Broken glass or blown double-glazed units
- Cracking that needs a structural engineer to look at it
- A dripping trap, valve or pipe behind a fitting
If you are not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer.
Surfaces we seal
- External facade joints
- Window and door perimeters
- Washrooms and tea points
- Kitchen worktops and splashbacks
- Movement joints in walls and floors
- Floor and threshold joints
What the job involves on each surface
Window and door perimeters
Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control, and we install to the specification.
How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Joint width, depth and condition
- Working within restricted access windows
- The total length or number of joints
- How accessible the joints are
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.
What we need to price the job
We can often quote from photos and a few details. It helps to include:
- The product your specification calls for
- Drawings or a marked-up plan, if available
- Whether the building will be occupied during the work
- Your programme or deadline
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call 01277 525 020 or email drawings and photos.
Other services in Bexleyheath
What Bexleyheath’s businesses ask us to seal
Bexleyheath has three care or nursing homes no more than 2 miles away. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor. London premises normally come with a building manager, booked loading and house rules for contractors. We fit into those systems and phase the work so the building keeps operating.
Offices at parks like Old Bexley Business Park, 1.3 miles to the south-east of Bexleyheath, have receptions, kitchens and glazed partitions where a tidy joint matters. For premises near Bexleyheath station, which lies north-west of Bexleyheath, footfall is part of the plan: work is phased so shops and offices keep trading. A business with units at Old Bexley Business Park and Bourne Industrial Park needn’t use two contractors for its sealant.

Questions we’re asked in Bexleyheath
Do you take on jobs in Bexleyheath where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
Will our hotel in Bexleyheath need to close for the work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Is Bexleyheath in your area?
Yes. Bexleyheath falls within our area, and the simplest way to start is to ring 01277 525 020 or email us.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
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 checks let you plan resealing before leaks or damage.
What do you need from us to quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.
