Commercial mastic work in Whitchurch

Most of the buildings we seal stay open while we’re there. Work is scheduled around the site hours and access windows you give us; phased work can also be planned so areas stay in use. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on external facade joints, floor and threshold joints and window and door perimeters, and what we’re called in for most is wall and floor joints that have lost their seal and frame mastic that has hardened and come away from the wall. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Whitchurch is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Business units in the countryside around places like Whitchurch are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

For a hotel such as Priory Hotel, under half a mile south-west of Whitchurch, the colour of a joint at the bar or the bath matters to the look of the room.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Whitchurch, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. You send photographs, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.

  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Advice

FAQs: Whitchurch

Is a smaller place like Whitchurch outside your area?

Not at all: smaller places are covered as well as towns. 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.

What paperwork can you provide for a job in Whitchurch?

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

Can areas stay open during the work?

Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.

Can you take on work for an FM or managing agent?

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

What guarantee do you give on resealing?

Each job sits under our 12-month guarantee. Keeping joints clean and inspected helps them last well beyond that.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Do you take on multi-site sealant work?

Yes, we can. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.

When it isn’t the sealant

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

  • Faulty windows rather than failed perimeter sealant
  • A dripping trap, valve or pipe behind a fitting
  • Cracking that needs a structural engineer to look at it

If you are not sure, just call 01277 525 020 or email us and we’ll give you a straight answer.

Where we work in Whitchurch

  • Movement joints in walls and floors

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Whitchurch can form part of a wider programme across Buckinghamshire.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

When to call us in Whitchurch

Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once, which is why regular inspection pays.

Things that normally lead to an enquiry:

  • A top-up bead over failed sealant, now lifting
  • Weathered facade sealant that no longer flexes
  • Messy, uneven beads from earlier work that let the building down
  • Frame mastic that has hardened and come away from the wall

Premises within reach of Aylesbury Vale Parkway station, 3.5 miles to the south of Whitchurch, often have busy frontages where joints are seen by everyone passing.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • What site paperwork they can supply
  • What the guarantee covers, and for how long
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

Cost factors for sealant joints

We price every job individually. The things that drive the figure:

  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers
  • Any access equipment needed
  • How much existing material needs removing

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Details that help us quote

We can often quote from photos and a few details. Please tell us:

  • When you need the work done
  • Drawings or a marked-up plan, if available
  • Any specification or named product
  • Access details, including height

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or send photos by email.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Act on the first lifting edges rather than waiting
  • Keep washroom and kitchen extraction working
  • Keep barriers up until the new sealant has cured
  • Brief cleaning contractors to avoid scourers and blades on sealant

Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. If that happens, phone 01277 525 020 or send details through our quote form and we will price putting it right.

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.
