Your questions answered

Must a hotel around Egham close while you work?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we will plan around them.

Is The Green Business Centre, near Egham, within your area?

Yes. Estates, retail parks and business parks around Egham, The Green Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

Is your work guaranteed?

A 12-month guarantee covers the workmanship, starting at sign-off. Looking after the joints as we advise helps them last.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Which site documents can you send us?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Commercial sealant contractors in Egham, done properly

Commercial occupiers rarely want a floor out of action for sealant work. Work is scheduled around the site hours and access windows you give us. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on window and door perimeters, washrooms and tea points and kitchen worktops and splashbacks, and the usual reasons a site gets in touch are smeared sealant across finishes from a rushed job and gaps behind commercial kitchen worktops and sinks. Most enquiries from Egham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A lot of what we do in Egham is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

In a town the size of Egham, commercial buildings tend to be high-street shops, offices over shops, schools, care homes and small industrial units. Shopfronts, kitchens, washrooms and frames all have sealant that ages, and where a frontage is on show, a matched colour keeps it looking right.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What sets the cost

Before we quote, we look at:

  • How much there is to seal
  • Phasing around occupants
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • The asbestos register, for older buildings
  • How the joints are reached, and at what height
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or send photos by email with what you know.

Commercial premises in Egham

Egham has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it. Egham sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

Offices and shops close to stations such as Egham station, less than half a mile east of Egham, tend to be busy all day, so sealant work is planned around opening hours. Occupiers with premises at both The Green Business Centre and Hawthorne Trade Park could have the sealant at each handled under one quote. For tenants and agents on sites such as The Green Business Centre, 0.8 miles to the north-east of Egham, office fit-outs, reception joints and window perimeters are the usual sealant work.

Egham is about 6 miles south-east of Slough, in Surrey. Anywhere in TW20, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 379 places across Surrey fall within our area, including Egham. We also cover Reading, some 19 miles away.

Postcode districts covered here: TW20 and TW18. If your site is on Station Road, Church Road and High Street or close by, send details and we’ll quote for sealant joints. Egham sits on or close to the A30 and A308, which helps when planning parking and deliveries for the job. Just outside Egham, we also work in Englefield Green (1 mile west), Hythe End (1 mile north), Egham Hythe (1 mile east), Stroude (1 mile south) and Thorpe (2 miles south-east). Further afield, our area takes in Guildford (13 miles south), Woking (8 miles south), Camberley (10 miles south-west), Epsom (14 miles south-east), Ewell (14 miles south-east) and Walton-on-Thames (7 miles south-east). Egham is one of the busier places in Surrey, and we take on sealant joints for its commercial and public buildings.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • A dripping trap, valve or pipe behind a fitting
  • Broken glass or blown double-glazed units
  • Suspect materials that need testing and specialist removal

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

  • Washrooms and tea points
  • Window and door perimeters
  • External facade joints
  • Kitchen worktops and splashbacks
  • Movement joints in walls and floors
  • Floor and threshold joints

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. In a town such as Egham, most jobs are single buildings. Your photos, drawings or a site visit come first, followed by a fixed quote.

  1. First, details come to us: photos, drawings or a schedule of the areas.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance
  • Let us know about inductions and permits

Related advice

What happens if it’s left?

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, and they’re where most failures begin. It shows over the following seasons rather than at handover. In a town like Egham, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.

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 will have a fixed figure to work with.

Why appoint us

  • Work to your specification and the manufacturer’s guidance
  • RAL and finish matching where the product range allows
  • CHAS accredited contractor
  • One contact handling all your sites

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Note dates and locations of sealant work for future planning
  • Act on the first lifting edges rather than waiting
  • Check sealant as part of routine building inspections
  • Keep abrasive pads and scrapers off resealed joints

Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks. Should something look amiss, you can call the office on 01277 525 020 or send photos by email and send a picture.

A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. 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.
