Common questions from Gubblecote clients

Does your area include sites such as Old Airfield Industrial Estate, near Gubblecote?

Yes. We cover Gubblecote and the area around it, including industrial estates, business parks and retail parks such as Old Airfield Industrial Estate. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is a smaller place like Gubblecote outside your area?

Not at all. Gubblecote 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.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure.

How do you keep disruption to occupiers down?

It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we will plan the job around it.

What about asbestos in old mastic?

We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility and removing it isn’t something we do.

Do you hold CHAS accreditation?

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

Do you work directly for building managers?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.

Sealant specialists in Gubblecote

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested. We work on window and door perimeters, external facade joints and kitchen worktops and splashbacks, and what we’re called in for most is frame mastic that has hardened and come away from the wall and wall and floor joints that have lost their seal. One point of contact handles commercial sealant work in Gubblecote from the first photos to the final walk-round, for single jobs and planned programmes alike.

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

Commercial sealant work around smaller places like Gubblecote tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Commercial sealant contractors around Gubblecote: what changes locally

Gubblecote sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. At about 34 miles from central London, Gubblecote is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site.

If you have premises on more than one site, say at Old Airfield Industrial Estate and Aesop Business Park, one contractor and one quote can cover both. Offices and shops close to stations such as Cheddington station (2.4 miles north-east of Gubblecote) tend to be busy all day, so sealant work is planned around opening hours.

Gubblecote is about 6 miles east of Aylesbury, in Hertfordshire. Businesses, contractors and managing agents in Gubblecote can call on us for sealant joints, as part of our coverage of Hertfordshire. We work across 371 places in Hertfordshire, from busy centres to rural villages. There’s a separate page for Oxford, roughly 24 miles from Gubblecote.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Report cracked or peeling sealant early
  • Note dates and locations of sealant work for future planning
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Make sure ventilation in wet areas is switched on and working

Give fresh sealant time to cure before it’s cleaned, wetted or walked past. Cure time varies with the product, conditions and depth of the joint, so we confirm it for each area at handover. Keeping signs or barriers up until then protects the finish.

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. 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. Smaller jobs around Gubblecote can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  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.

Preparing the site

  • Make sure the joints can be reached
  • Arrange parking or a loading space
  • Point out any areas we must not close

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Faulty windows rather than failed perimeter sealant
  • Cracking that needs a structural engineer to look at it
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Where we work in Gubblecote

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

When to call us in Gubblecote

A good share of the joints we inspect were topped up instead of being renewed. 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.

Common reasons buildings call us in:

  • Weathered facade sealant that no longer flexes
  • Smeared sealant across finishes from a rushed job
  • Frame mastic that has hardened and come away from the wall
  • Mouldy silicone around WCs, urinals and vanity tops

Trade counters and showrooms on estates such as Old Airfield Industrial Estate (to the north-east of Gubblecote) need neat joints where clients see them.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Whether old or failed sealant will be cut out, not overlaid
  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Cost factors for sealant joints

These are the things that shape the price:

  • Distance, for remote addresses
  • Phasing around occupants
  • Quantities, in metres or numbers
  • Access and working height

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • When you need the work done
  • Anything awkward about access or site hours
  • Drawings or a marked-up plan, if available
  • What the building is and how it’s used

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or send details through our quote form.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
