Common problems we fix in Chicheley

A split down the middle of the bead tells a different story. That typically means the joint stretched further than the product could cope with: a bead laid too thin, an over-stretched joint or the wrong movement class. Replacing it like for like rarely holds, so width, depth and product are checked before we quote.

These are often picked up first by site or facilities staff:

  • Layers of sealant, all of them failing
  • Greasy, split joints in a kitchen or tea point
  • Expansion joints with the sealant torn out
  • Untidy joints in a reception, shop floor or lobby

Parks like Cromwell Business Park (to the south-west of Chicheley) see tenants come and go, and every move-in brings joints to seal.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their plan for phasing and protecting the area
  • Who will actually carry out the work

Our contractor checklist

Sealant applicators in Chicheley

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. If you’re dealing with expansion joints with the sealant torn out and external beads that have gone brittle and cracked, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Chicheley is the same: the right product in a properly prepared joint.

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

A job in a smaller place like Chicheley is usually a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Keeping the joints sound

To get the most from the new sealant:

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Put external and wet-area joints on a regular inspection round
  • Log reseals in the O&M or maintenance records
  • Make sure ventilation in wet areas is switched on and working

In washrooms and kitchens, extraction makes a real difference to sealant life. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.

Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Shops, offices and hotels in and around Chicheley

The area within 2 miles of Chicheley holds several hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme; work is planned so the hotel keeps trading. Chicheley sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Whatever the building in Chicheley, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Questions we are asked in Chicheley

Do hotels near Chicheley have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

Do you cover business parks and estates near Chicheley, such as Cromwell Business Park?

Yes. We cover Chicheley and the area around it, including industrial estates, business parks and retail parks such as Cromwell Business Park. Photos and a short description are enough for a first look.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Do you work in Chicheley?

Yes. Chicheley falls within our area, and you can call the office on 01277 525 020 or email us to get started.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Is it OK to apply fresh sealant over existing beads?

Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Broken glass or blown double-glazed units
  • Structural cracks or movement the joints weren’t designed for

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

Joints and surfaces we work on

  • Washrooms and tea points
  • Window and door perimeters
  • Floor and threshold joints

  • Kitchen worktops and splashbacks
  • External facade joints

Our process

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Chicheley can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. You send photographs, drawings or a list of the joints and areas involved, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work
  • Let us know about inductions and permits
