Our commercial sealant contractors service in Hertfordshire

We have applied sealant on commercial sites for over 20 years, and the documents buyers ask for are ready: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. We work on kitchen worktops and splashbacks, external facade joints and movement joints in walls and floors, and the failures we’re asked to look at most are movement joints packed with grit and debris and hardened, chalky sealant on south-facing or exposed elevations.

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.

First, details reach us through the quote form or 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.
Every failed bead is removed rather than covered.
Each joint gets a suitable sealant, laid to depth and tooled.
We check the work with you, and the 12-month guarantee starts.

How we quote

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Shops, offices and hotels in Hertfordshire

Across Hertfordshire, from Watford, Hemel Hempstead and Stevenage to the smaller places between, commercial buildings run from high-street shops and offices to hotels, schools and business parks. 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 Hertfordshire starts with access, parking and site rules.

Watford: For a shop at a centre such as Harlequin Centre, 0.6 miles south of Watford, tidy joints at counters and displays matter as much as the fixtures. Shops and cafés around stations like Watford Junction station (under half a mile east of Watford) trade from early, so work is timed around them.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

Suspect materials that need testing and specialist removal
Misted, cracked or failed glazing units (a glazier’s job)
Walls or slabs moving more than any sealant can take

Different surfaces, different methods

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photographs or a site visit tell us what’s needed, with colours confirmed for the product chosen.

How the quote is worked out

These are the things that shape the price:

The size and state of each joint
Any access equipment needed
Removal of failed or old sealant
Site requirements such as inductions and permits

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

Drawings or a marked-up plan, if available
How the joints are reached, and at what height
What the building is and how it’s used
The postcode of the building

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, call 01277 525 020 or email a schedule or drawings.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Certain joints really need a specialist: for instance 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.

Signs you need commercial sealant contractors

Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.

What tends to prompt an enquiry:

Weathered facade sealant that no longer flexes
Leaks that seem to come through a sealant line
Mouldy silicone around WCs, urinals and vanity tops
Messy, uneven beads from earlier work that let the building down

Questions about Hertfordshire

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

Will the building have to shut during the work?

Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing.

How many days will you need on site?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What site paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
