Sealant applicators in Colney Butts
Inside a commercial building, sealant does a lot of quiet work: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike. If you are dealing with wall and floor joints that have lost their seal and a top-up bead over failed sealant, now lifting, we can help. For commercial sealant work in Colney Butts, you deal with one contact from quote to sign-off, whether it’s one building or several.
On a typical commercial building in Colney Butts, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
Around smaller places such as Colney Butts, small firms often work from converted barns, yards and rural units. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.
A 12-month guarantee applies to all our work in Hertfordshire. Should something we installed fail, phone 01277 525 020 or email the details over and we will come back to it.

What Colney Butts’s businesses ask us to seal

Colney Butts sits in one of the drier corners of the country, the South East. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.
Sites a few miles apart, such as Fisher Industrial Estate and Wiggenhall Industrial Estate, can share one programme and one point of contact. A hotel such as Best Western White House Hotel (under half a mile north of Colney Butts) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. Industrial estates such as Fisher Industrial Estate (to the south-east of Colney Butts) have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Aftercare for building managers
To get the most from the new sealant:
- Keep washroom and kitchen extraction working
- Don’t let cleaning or traffic back on before the cure time is up
- Check the asbestos register before anyone disturbs old sealant in an older building
- Ask cleaners to use a soft cloth and mild cleaner on sealant
Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed. Where work has disturbed a joint, just ring 01277 525 020 or email us for a quote.
Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.
When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- A dripping trap, valve or pipe behind a fitting
- Old mastic that tests positive for asbestos
- Faulty windows rather than failed perimeter sealant
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.
Surfaces we seal
- Window and door perimeters
- Floor and threshold joints
- Washrooms and tea points
- Movement joints in walls and floors
- External facade joints
- Kitchen worktops and splashbacks
Common questions from Colney Butts clients
Does a hotel in Colney Butts need to shut while its sealant is renewed?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Is Colney Butts too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
What guarantee do you give on resealing?
Each job sits under our 12-month guarantee from handover. Keeping joints clean and inspected helps them last well beyond that.
How do we get a quote?
Start with whatever information is to hand. Questions or a site visit follow where needed.
Can one contractor look after sealant on all our buildings?
Yes. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you check for asbestos before removing sealant?
Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Surface by surface
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. We plan around the access windows the store gives us, phasing areas so the shop floor stays usable.
Washrooms and toilets
Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, with phased work so some facilities stay open.
How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
- Quantities, in metres or numbers
A quote for sealant joints depends on quantities, condition and access. Call for a quote.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Access details, including height
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
