Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. In a town such as Crowborough, most jobs are single buildings. We start with your photographs, drawings or a site visit, then send a fixed quote.
- First, details come to us: photographs, drawings or a schedule of the areas.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- We strip the failed bead and prepare both faces of the joint.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Each area is inspected, signed off and backed by our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Let us know about inductions and permits
- Tell us which areas need to stay in use

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Advice
Commercial sealant contractors in Crowborough
On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Outside, it closes facade joints, frame perimeters and movement joints against the weather. We deal with internal and external sealant joints alike, picking the product for each location rather than one tube for everything. Site teams most often ask us about smeared sealant across finishes from a rushed job and frame sealant that has cracked, shrunk or pulled away, on window and door perimeters, external facade joints and washrooms and tea points. A specialist sealant contractor works differently from a general builder: in Crowborough, that means joint design, primers and backing rod as standard.
In an occupied building in Crowborough, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.
Many businesses in towns like Crowborough work from older buildings that have been altered more than once. Where old meets new there are junctions between brick, render, timber and aluminium, and each needs the right sealant.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Looking after the joints
A few simple habits keep the new joints working:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Keep abrasive pads and scrapers off resealed joints
- Have extract fans checked so wet areas dry out
- Check sealant as part of routine building inspections
Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. If that happens, call 01277 525 020 or email us and we will price putting it right.
Occupiers often notice failing sealant before the facilities team does, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.
Sealant on show in Crowborough’s commercial buildings
The South East is one of the drier parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Central London is about 33 miles from Crowborough. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. If you have premises across the region, one contractor can cover them all.
For tenants and agents on sites such as Crowborough Business Park, 0.6 miles north of Crowborough, office fit-outs, reception joints and window perimeters are the usual sealant work. Sites a few miles apart, such as Crowborough Business Park and Beacon Business Park, can share one programme and one point of contact. For premises near Crowborough station, 1 mile to the south-east of Crowborough, footfall is part of the plan: work is phased so shops and offices keep trading.

What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Location, for remote and island sites
- Access and working height
- The size and state of each joint
- Whether the work must be split into stages
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
What we need to price the job
We can often quote from photos and a few details. It helps to include:
- The postcode of the building
- Asbestos survey details if the building is older
- Any specification or named product
- How the joints are reached, and at what height

Leave it or put it right?
Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation. You notice the difference years later, not on the day. In a town such as Crowborough, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Renewing them before water gets in protects the fabric.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Your questions answered
Is Crowborough Business Park, near Crowborough, within your area?
Yes. Estates, retail parks and business parks around Crowborough, Crowborough Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Do you offer colour-matched sealant for buildings in Crowborough?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Is it OK to apply fresh sealant over existing beads?
The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Do you work directly for building managers?
Yes. A large share of our work comes through facilities managers, managing agents and landlords. We can work to your instruction process and site rules.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Misted, cracked or failed glazing units (a glazier’s job)
- Roof leaks that only look like a joint problem
- Walls or slabs moving more than any sealant can take
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly before you book.
