After the work

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

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Check sealant as part of routine building inspections
  • Keep barriers up until the new sealant has cured
  • Make sure ventilation in wet areas is switched on and working

Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life.

Sealant installed at the same time typically fails in sequence. A few splits this year normally mean more next year. We’ll tell you which sealant joints need doing first and which can wait.

Commercial sealant contractors for commercial buildings in Great Hollands

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface, and a backing rod limits the depth to give the sealant room to work. We work on movement joints in walls and floors, floor and threshold joints and washrooms and tea points, and the usual reasons a site gets in touch are external beads that have gone brittle and cracked and frame sealant that has cracked, shrunk or pulled away. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Great Hollands it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Occupied buildings in Great Hollands need the work phased: washrooms in turn, floors in sections and entrances kept open.

Small businesses near places like Great Hollands frequently occupy converted farm buildings. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

When to call us in Great Hollands

When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.

Clients usually get in touch after noticing something like this:

  • Greasy, split joints in a kitchen or tea point
  • A top-up bead over failed sealant, now lifting
  • Frame sealant that has cracked, shrunk or pulled away
  • Untidy joints in a reception, shop floor or lobby

Offices and shops close to stations such as Bracknell station, 1.3 miles to the north-east of Great Hollands, tend to be busy all day, so sealant work is planned around opening hours.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • Are they CHAS accredited or on Constructionline?
  • What the guarantee covers, and for how long
  • Do they follow the manufacturer’s priming guidance?

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • A failed roof covering or waterproofing membrane
  • Water from a services leak rather than a joint
  • Cracking that needs a structural engineer to look at it

If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think before you book.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Questions about Great Hollands

Is Great Hollands too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will our hotel in Great Hollands need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we will plan around them.

Do you work directly for building managers?

Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

How do we get a quote?

Send photos, drawings or a list of locations through the quote form on this site. If a visit is needed we’ll book one, and a fixed quote follows.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Work in places the size of Great Hollands is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Send details through our quote form, or ask for 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. Old sealant is cut out completely, never sealed over.
  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.

What the job involves on each surface

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean, which matters when environmental health officers look at a kitchen. We seal to a neat, cleanable finish and work around service times you agree with us.

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. We plan around the access windows the store gives us, working in sections where that helps.
