Commercial sealant contractors near Inkpen

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

After the work

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

  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Have extract fans checked so wet areas dry out
  • Deal with small splits before they become leaks
  • Keep barriers up until the new sealant has cured

Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

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.

About our commercial sealant contractors in Inkpen

Inside a commercial building, sealant does a lot of quiet work: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Outside, it closes facade joints, frame perimeters and movement joints against the weather. Our applicators work on both the inside and the outside of the building. If you are dealing with mouldy silicone around WCs, urinals and vanity tops and weathered facade sealant that no longer flexes, we can put it right, on window and door perimeters, external facade joints and movement joints in walls and floors alike. One point of contact handles commercial sealant work in Inkpen from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Multi-site clients with buildings in and around Inkpen can put several sites on one programme, with one quote format and one point of contact.

A job in a smaller place like Inkpen is normally a single building. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Inkpen may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

Commercial premises in Inkpen

Inkpen lies roughly 60 miles out from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. Rainfall across the South East, Inkpen included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

For premises near Kintbury station, which lies north-east of Inkpen, footfall is part of the plan: work is phased so shops and offices keep trading.

Inkpen is about 6 miles west of Newbury, in West Berkshire. Our applicators travel to Inkpen for work on sealant joints. Inkpen is one of 140 places we cover in West Berkshire for sealant joints. Sites around Reading have their own page, roughly 22 miles from Inkpen.

We take on sealant joints across the RG17 postcode area, whatever the building. Buildings on Folly Road, Post Office Road and Robins Hill are within our area. Just outside Inkpen, we also work in Inkpen Common (1 mile south-east), Upper Green (1 mile south), Hell Corner (1 mile east), Lower Green (1 mile west) and Kintbury (2 miles north-east). Further afield, our area takes in Newbury (6 miles east), Thatcham (9 miles east), Speenhamland (6 miles east), Hungerford (3 miles north-west), Lambourn (9 miles north) and Shaw (7 miles east).

Do you need commercial sealant contractors in Inkpen?

Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.

Any of the following is a good reason to get the joints checked over:

  • A top-up bead over failed sealant, now lifting
  • Water staining near frames, panels or ceilings
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Window and door perimeter joints that have cracked open

Parks like Stype Business Centre, 3 miles to the west of Inkpen, see tenants come and go, and every move-in brings joints to seal.

What to look for in a quote

  • How they handle RAMS and site documents
  • Their plan for phasing and protecting the area
  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?

Choosing a commercial sealant contractor

What sets the cost

To price the job, we consider:

  • Travel to remote or island sites
  • Phasing around occupants
  • Joint width, depth and condition
  • How much there is to seal

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Clear photographs of the problem areas
  • The type of building and who uses it
  • Asbestos survey details if the building is older
  • The site address and postcode

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to phone 01277 525 020 or email drawings and photos.

What happens if it’s left?

It can be tempting to hold sealant work back until the next refurbishment. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme. Halls, stores and units around places like Inkpen may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Questions we’re asked in Inkpen

Can you work at a site such as Stype Business Centre, by Inkpen?

Yes. We cover Inkpen and the area around it, including industrial estates, business parks and retail parks such as Stype Business Centre. A few photos and the unit address let us price the work.

Is Inkpen off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you work directly for building managers?

Yes. You can send details through our quote form, and we will confirm any paperwork you need with the quote.

Is the old sealant taken out first?

Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip, and the faces are brought back to sound, dry material before resealing.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Which site documents can you send us?

The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.

How the job changes by surface

Movement joints in walls and floors

Movement joints in walls and floors let the structure expand and contract. When the seal fails, debris gets in and the joint stops working. The joints are resealed using a sealant matched to the movement and any traffic.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photos or a site visit tell us what’s needed, with colours confirmed for the product chosen.
