How commercial sealant contractors works in Kent

We have applied sealant on commercial sites for over 20 years, and the paperwork side is in order: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. The enquiries we see most involve hardened, chalky sealant on south-facing or exposed elevations and sanitary sealant that has gone black and patchy, across movement joints in walls and floors, window and door perimeters and external facade joints.

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you.

We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
We work out why the joints have failed and fix a quote for the agreed scope.
We plan around your site hours and access windows, phasing the work where areas have to stay in use.
The failed bead is removed and the joint faces cleaned until they’re sound and dry.
Backing and primer go in where needed, then the chosen sealant is applied and tooled.
Finished joints are checked with you and handed over with our 12-month guarantee.

Pricing in Kent

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Around Maidstone

We work on buildings around Paper Makers Arms, Maidstone Grammar School and St Philip's Church and the streets around them. Other local landmarks include River Len LNR (less than half a mile north-east), South Borough Primary School (less than half a mile south) and St Augustine Academy (1.2 miles west). Maidstone’s nearest station is Maidstone West station, about 0.6 miles north-west of the centre. Well-known places in the area include Maidstone Carriage Museum (under half a mile north-west) and Oakwood Hospital (1.8 miles west). Not far away are Burham Down and Boxley Hills.

Shops, offices and hotels in Kent

From Maidstone, Ashford and Canterbury outwards, Kent has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. Because we cover all of it, multi-site occupiers can bring every building under one quote.

We work across Greater London and the South East counties, and every job in Kent starts with access, parking and site rules. Along the coast in Kent, hospitality buildings tend to be busiest in the summer months, which makes the quieter months a good time for sealant work.

Maidstone: Offices and shops close to stations such as Maidstone West station, 0.6 miles to the north-west of Maidstone, tend to be busy all day, so sealant work is planned around opening hours. Refits at hotels like Stone Court Hotel, less than half a mile north of Maidstone, bring joints at vanity tops, bars and reception desks that guests see every day.

Quoting for work in Kent

Your fixed quote is built from the real scope. It takes account of:

The product specified
Location, for remote and island sites
The site’s rules and procedures
Whether old sealant has to be cut out first

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

However big the job, these details speed things up:

The postcode of the building
The product your specification calls for
Photos of the joints, close up and from further back
Whether the building will be occupied during the work

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.

Why deal with it now?

Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We will suggest an order, worst sealant joints first.

What your quote should include

Whether old or failed sealant will be cut out, not overlaid
Is depth set with backing rod, or bond-breaker tape in shallow joints?
Whether their applicators hold CSCS cards
Whether primer will be used where the manufacturer specifies it

General trades versus a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

For most general trades, sealant is a sideline. 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.

Aftercare for building managers

After handover, these steps help:

On pre-2000 buildings, share the asbestos information before work starts
Make sure ventilation in wet areas is switched on and working
Add sealant to the planned maintenance inspection list
Act on the first lifting edges rather than waiting

New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth. Leaving the area closed until then keeps the bead neat.

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

A failed roof covering or waterproofing membrane
Removing asbestos-containing materials (a licensed or specialist contractor’s job)
Walls or slabs moving more than any sealant can take

Your questions answered

Do you work for facilities managers and managing agents?

Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.

Does commercial sealant work come with a guarantee?

Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. For bigger or phased jobs, we will set out a timescale with the quote.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Which site documents can you send us?

Send your site requirements with the enquiry. From you, we will need the asbestos information for older buildings and any site rules.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
