Commercial sealant contractors in St Nicholas, done properly
Having a single contact for all your sites makes sealant far simpler to manage. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in St Nicholas, ring 01277 525 020 or email drawings and photos with the site addresses. Most enquiries involve layers of sealant, all of them failing and sanitary sealant that has gone black and patchy, on kitchen worktops and splashbacks, washrooms and tea points and floor and threshold joints. For commercial sealant work in St Nicholas, you deal with one contact from quote to sign-off, whether it’s one building or several.
Occupied buildings in St Nicholas need the work phased: washrooms in turn, floors in sections and entrances kept open.
Small businesses near places like St Nicholas frequently occupy converted farm buildings. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for sealant joints
The price varies from site to site. It mainly depends on:
- Location, for remote and island sites
- Access and working height
- The size and state of each joint
- Working within restricted access windows
A quote for sealant joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Sending details for a quote
However big the job, these details speed things up:
- Rough lengths or quantities, or drawings if you have them
- Access details, including height
- What the building is and how it’s used
- Asbestos survey details if the building is older
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, call 01277 525 020 or email the details over.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a site in St Nicholas, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- 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 we need from you
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work
- Clear stock, furniture or equipment away from the joints

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Misted, cracked or failed glazing units (a glazier’s job)
- Walls or slabs moving more than any sealant can take
- Suspect materials that need testing and specialist removal
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly.
Surfaces we seal
- Washrooms and tea points
- Window and door perimeters
- External facade joints
- Floor and threshold joints
- Kitchen worktops and splashbacks
- Movement joints in walls and floors
Questions we are asked in St Nicholas
Is St Nicholas too far out for you?
No. Places such as St Nicholas are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Monkswood Retail Park, near St Nicholas?
Yes, sites like Monkswood Retail Park are within our area, along with the rest of St Nicholas. Send details of the unit and the work through our quote form for a quick quote.
Is failed sealant stripped out, or sealed over?
Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you check for asbestos before removing sealant?
It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Also in St Nicholas
Leave it or put it right?
Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement, and we will say so if the frame or fitting is life-expired. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Work for main contractors and building owners
We work for building owners and managing agents on everything from one building to a spread of sites around St Nicholas. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Put external and wet-area joints on a regular inspection round
- Keep washroom and kitchen extraction working
- Check joints after other trades have worked nearby
- Don’t let cleaning or traffic back on before the cure time is up
Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just phone 01277 525 020 or use the quote form for a quote.
Sealant rarely fails all at once across a building. A few splits this year typically mean more next year, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.
