Commercial sealant contractors for businesses in Tilehurst

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Leave it or put it right?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement. For buildings in places like Tilehurst, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Why us?

  • Colour agreed before work starts
  • Standard and matched colours in many product ranges
  • Work carried out by CSCS-carded applicators
  • Joints cleaned back to sound surfaces

Commercial mastic work in Tilehurst

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure typically announces itself as a stained ceiling or an unhappy tenant. We are commercial sealant applicators for FMs, managing agents, landlords and contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. Site teams most often ask us about frame sealant that has cracked, shrunk or pulled away and water staining near frames, panels or ceilings, on washrooms and tea points, movement joints in walls and floors and floor and threshold joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Tilehurst, that means joint design, primers and backing rod as standard.

In Tilehurst, as anywhere, the first joints to go are typically the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

In a smaller place such as Tilehurst, commercial buildings are usually a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. They’re not big jobs one by one, but their joints need the same preparation as anywhere.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Common questions from Tilehurst clients

Does your area include sites such as Oxford Road Business Park, near Tilehurst?

Yes. We cover Tilehurst and the area around it, including industrial estates, business parks and retail parks such as Oxford Road Business Park. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Will our hotel in Tilehurst need to close for the work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.

How long does a job like this take?

That varies with the scale of the job, though a typical visit normally takes a few hours for one area, or a planned series of visits across a bigger building. For bigger or phased jobs, we’ll set out a timescale with the quote.

How do you keep disruption to occupiers down?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we will work around it.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can you handle sealant work across several sites?

Yes. Give us the sites and the scope at each, and we will put together a fixed quote and a sensible order of work.

Surface by surface

Fire-rated seals where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, so we’ll flag it if the detail needs a different product.

Commercial kitchens and tea points

In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. Proper degreasing comes before any new sealant, and a hygienic or food-safe sealant is used where food contact is possible.

What Tilehurst’s businesses ask us to seal

Rainfall across the South East, Tilehurst included, is lower than in many parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Tilehurst is about 41 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

Sites a few miles apart, such as Oxford Road Business Park and Norcot Industrial Estate, can share one programme and one point of contact. For premises near Tilehurst station, 0.8 miles to the north of Tilehurst, footfall is part of the plan: work is phased so shops and offices keep trading. Offices at parks like Oxford Road Business Park, 0.8 miles north-east of Tilehurst, have receptions, kitchens and glazed partitions where a tidy joint matters.

Tilehurst is about 3 miles west of Reading, in Reading. Tilehurst sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 17 places across Reading fall within our area, Tilehurst among them.

We take on sealant joints across the RG31 and RG30 postcode area. For a building on Ash Road, Tyle Road and Riley Road or nearby, send details and we will quote for sealant joints. Sites close to Tilehurst are covered too, including Tilehurst Within (1 mile south-east), Norcot (1 mile east), Little Heath (1 mile west), Horncastle (1 mile south-east) and Purley on Thames (1 mile north). Bigger towns within reach include Reading (3 miles east), Caversham (3 miles east), Newtown (4 miles east), Whitley Wood (4 miles south-east), Whitley (4 miles south-east) and Caversham Park Village (4 miles east).

From enquiry to sign-off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a site in Tilehurst, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. You send photos, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Site hours, access windows and the order of areas are agreed before we start.
  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. We walk the completed areas with you and sign them off under the 12-month guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Look at the sealant around anything that has been moved or replaced
  • Keep a record of which joints were resealed and when
  • Keep washroom and kitchen extraction working
  • On pre-2000 buildings, share the asbestos information before work starts

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. Your maintenance team can look at extract fans at the same time.

Once sealant fails in a movement joint, grit and debris get in. 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.

Commercial clients in Tilehurst

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Roof leaks that only look like a joint problem
  • Old mastic that tests positive for asbestos

If you are not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer before you book.

Surfaces we seal

  • Kitchen worktops and splashbacks
  • Floor and threshold joints
