How commercial sealant contractors works in DA16
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: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in DA16, call the office on 01277 525 020 or use the quote form with the site addresses. We work on external facade joints, washrooms and tea points and movement joints in walls and floors, and the usual reasons a site gets in touch are shrunken sealant along kitchen worktops and splashbacks and sanitary sealant that has gone black and patchy.
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
What affects the price in DA16
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Where commercial joints are in DA16
From Welling, Bexleyheath and Blackfen outwards, DA16 has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. We cover the whole area, so occupiers with several sites can use one contractor and one point of contact.
All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, and every job in DA16 starts with access, parking and site rules.
Welling: Occupiers with premises at both Old Bexley Business Park and Gateway Business Centre could have the sealant at each handled under one quote. Like every part of Greater London, Welling is covered by the ULEZ, so vehicle access, loading and parking are planned before the first visit.
What sets the cost
We price every job individually. The main factors are:
- Induction, permit and paperwork requirements
- Location, for remote and island sites
- The product specified
- Quantities, in metres or numbers
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- The type of building and who uses it
- Where the site is, with the postcode
- Photos of the joints, close up and from further back
- Any specification or named product
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Leave it or put it right?
Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. Splitting the scope into now and later is often the sensible compromise.
What your quote should include
- How they’ll work around occupants
- Their approach to joint depth and backing
- How the existing material will be dealt with
- Their public liability cover
Keeping the joints sound
Once the work is signed off, these steps help:
- Deal with small splits before they become leaks
- Keep a record of which joints were resealed and when
- Check sealant as part of routine building inspections
- Keep barriers up until the new sealant has cured
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.
Tenants and staff spot black or split sealant quickly. Planned replacement saves fielding the same complaint again and again.
Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Signs you need commercial sealant contractors
If only one face has lost its grip, that’s an adhesion failure. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. It’s one of the commonest faults we find on earlier work.
Clients normally get in touch after noticing something like this:
- Shrunken sealant along kitchen worktops and splashbacks
- Mouldy silicone around WCs, urinals and vanity tops
- Untidy joints in a reception, shop floor or lobby
- Water staining near frames, panels or ceilings
Your questions answered
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Does weather matter for sealant 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.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Is it OK to apply fresh sealant over existing beads?
Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes a few hours to several days on most single sites, depending on joint lengths and access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member.
