Commercial sealant contractors in Wickham, done properly

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). We work on external facade joints, movement joints in walls and floors and washrooms and tea points, and what we’re called in for most is frame sealant that has cracked, shrunk or pulled away and messy, uneven beads from earlier work that let the building down. Looking for mastic applicators who cover Wickham? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

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

Work in smaller places such as Wickham tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What the job involves on each surface

Facade and cladding joints

Facade joints move every day as panels warm and cool. 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.

Window and door perimeters

Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t, in a shade that suits the frame.

What sets the cost

We price every job individually. The main factors are:

  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Any access equipment needed
  • How much existing material needs removing

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • How the joints are reached, and at what height
  • When you need the work done
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or send photos by email.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Faulty windows rather than failed perimeter sealant
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Roof leaks that only look like a joint problem

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Surfaces we seal

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

Frontages, fit-outs and joints in Wickham

Wickham is in the South East, one of the UK’s drier regions. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. At about 58 miles from central London, Wickham is within reach of the capital. Business parks and retail centres are common around the capital’s motorway corridors. Firms with branches across the South East can use one contractor for every site.

Offices and shops close to stations such as Kintbury station, 3 miles south of Wickham, tend to be busy all day, so sealant work is planned around opening hours. Whatever the building in Wickham, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Wickham is about 6 miles north-west of Newbury, in West Berkshire. Wickham sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across West Berkshire, 140 places are covered, including Wickham. There’s a separate page for Reading, roughly 20 miles from Wickham.

Commercial sites across RG20 are covered for sealant joints. For a building on Welford Road, Baydon Road and Mant Close or nearby, we can quote for sealant joints. Nearby places we also cover include Easton (1 mile east), Weston (1 mile north), Clapton (1 mile south-west), East Shefford (2 miles north) and Shefford Woodlands (2 miles north-west) for sealant joints. Further afield, our area takes in Newbury (6 miles south-east), Thatcham (8 miles east), Speenhamland (5 miles south-east), Hungerford (4 miles south-west), Lambourn (6 miles north-west) and Shaw (6 miles south-east).

Work for main contractors and building owners

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 will confirm with the quote.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Wickham: questions and answers

Which documents can you supply for work in Wickham?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Can the sealant on our Wickham premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we will confirm what’s available for the product.

How do you choose the sealant?

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.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Can areas stay open during the work?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance.

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Rural sites near Wickham may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, or we arrange a site visit.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Preparing the site

Why it’s worth doing now in Wickham

Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. Older rural buildings around Wickham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why clients in Wickham choose us

  • A Constructionline member, so easy to vet
  • Colours chosen to suit frames, cladding or finishes where possible
  • Fully insured, including public liability cover
  • Old sealant cut out, never sealed over
