Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Common problems we fix in Hammersmith
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason.
These are often picked up first by site or facilities staff:
- Mouldy silicone around WCs, urinals and vanity tops
- External beads that have gone brittle and cracked
- A top-up bead over failed sealant, now lifting
- Frame sealant that has cracked, shrunk or pulled away
If you have premises on more than one site, say at Berghem Mews Business Village and Stable Way Industrial Estate, one contractor and one quote can cover both.
What your quote should include
- Their approach to joint depth and backing
- Will CSCS-carded applicators be on site?
- What the guarantee covers, and for how long
- Whether old or failed sealant will be cut out, not overlaid
About our commercial sealant contractors in Hammersmith
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. If you have smeared sealant across finishes from a rushed job and leaks that seem to come through a sealant line, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hammersmith, preparation and product choice get the time they need.
Quotes for commercial sealant in Hammersmith can come from photos and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Hammersmith: questions and answers
Do you cover business parks and estates near Hammersmith, such as Berghem Mews Business Village?
Yes, sites like Berghem Mews Business Village are within our area, along with the rest of Hammersmith. Send details of the unit and the work through our quote form for a quick quote.
Will our hotel in Hammersmith need to close for the work?
In most cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally takes a few hours to several days on most single sites, depending on joint lengths and access. For bigger or phased jobs, we will set out a timescale with the quote.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can one contractor look after sealant on all our buildings?
Yes. We regularly take on multi-site work and planned maintenance programmes, quoted per building or as a package.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
How the quote is worked out
What shapes the price:
- Distance, for remote addresses
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- Access and working height
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Anything awkward about access or site hours
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
- Your programme or deadline
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.
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Why act early in Hammersmith
Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. Resealing normally costs far less than renewal. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
