Commercial sealant contractors in Chieveley, done properly

Sometimes a split bead is a symptom rather than the cause. A leak near a frame edge can start in the frame, the cill or the cavity. We look before we quote and tell you plainly if sealant won’t solve it. The enquiries we see most involve shrunken sealant along kitchen worktops and splashbacks and frame mastic that has hardened and come away from the wall, on movement joints in walls and floors, kitchen worktops and splashbacks and washrooms and tea points. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Chieveley is the same: the right product in a properly prepared joint.

If you look after more than one building near Chieveley, the work can be planned as one programme, with one quote format and one point of contact.

Commercial sealant work around smaller places like Chieveley tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

Work we carry out in West Berkshire comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Broken glass or blown double-glazed units
  • Leaks from pipework, wastes or valves (that’s plumbing)

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly.

Where we work in Chieveley

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

Different surfaces, different methods

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, phasing the rooms so not every toilet is closed at once.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.

Should maintenance staff do it?

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Common questions from Chieveley clients

Is Chieveley too far out for you?

Not at all. Chieveley is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

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

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Can you supply RAMS and insurance details?

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

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Do you work directly for building managers?

Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Note dates and locations of sealant work for future planning
  • Keep barriers up until the new sealant has cured
  • Keep abrasive pads and scrapers off resealed joints
  • Check joints after other trades have worked nearby

Keep an eye out for other trades after we’ve gone. Shop refits, new services and replaced fittings often break the seal around them and the joint gets left open. Where work has disturbed a joint, just ring 01277 525 020 or email us for a quote.

Tenants and staff spot black or split sealant quickly, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.

What Chieveley’s businesses ask us to seal

Chieveley has several hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes. Chieveley sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

On estates like Red Shute Hill Industrial Estate, 2.1 miles south-east of Chieveley, the office and welfare end of each unit has its own sealant to maintain. Offices and shops close to stations such as Newbury Racecourse station, 4.5 miles south of Chieveley, tend to be busy all day, so sealant work is planned around opening hours.

Chieveley is about 5 miles north of Newbury, in West Berkshire. Chieveley sits inside our coverage and the rest of West Berkshire, with the same fixed quotes and 12-month guarantee as everywhere else. Chieveley is one of 140 places we cover in West Berkshire. There’s a separate page for Reading, about 15 miles away.

Commercial sites across RG20 are covered. If your site is on High Street, East Lane and Sowbury Park or close by, send details and we’ll quote for sealant joints. Just outside Chieveley, we also work in Downend (1 mile north), North Heath (1 mile west), World's End (2 miles north-east), Winterbourne (2 miles south-west) and Peasemore (2 miles north-west). Further afield, our area takes in Newbury (5 miles south), Thatcham (5 miles south-east), Burghfield Common (12 miles east), Speenhamland (4 miles south), Hungerford (9 miles west) and Fords Farm (13 miles east).

Quoting for work in Chieveley

Before we quote, we look at:

  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • When you need the work done
  • Photos of the joints, close up and from further back
  • Access details, including height
  • Whether an asbestos survey exists

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or email us.

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. If others near Chieveley need work, visits can be combined. A fixed quote is given before anything starts.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Flag any permit to work we will need
  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000

Ask for a 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 photos and a few notes.
