Sealant specialists in Grafty Green

Sometimes a split bead is a symptom rather than the cause. A leak near a frame edge can start in the frame, the cill or the cavity. We look before we quote and tell you plainly if sealant won’t solve it. If you are dealing with window and door perimeter joints that have cracked open and wall and floor joints that have lost their seal, we can put it right, whatever the surface. Most enquiries from Grafty Green start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Occupied buildings in Grafty Green need the work phased: we agree the order with you and hand back each area with its cure time.

Business units in the countryside around places like Grafty Green are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

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’re upfront about that.

Questions we are asked in Grafty Green

Will our hotel in Grafty Green need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

Is a smaller place like Grafty Green outside your area?

No. Places such as Grafty Green are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you supply RAMS and insurance details?

Let us know your requirements when you ask for a price, and we’ll confirm the RAMS, insurance and CSCS details with the quote. From you, we’ll need the asbestos information for older buildings and any site rules.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What about asbestos in old mastic?

It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.

How do we get a quote?

Send what you have, even a few photos and rough lengths. Questions or a site visit follow where needed.

Can one contractor look after sealant on all our buildings?

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

Building owners, agents and FMs in Grafty Green

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Grafty Green can sit alongside others in a wider programme.

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.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Why act early in Grafty Green

Reactive resealing, a leak at a time, tends to cost more overall than a plan. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in. Older rural buildings around Grafty Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why clients in Grafty Green choose us

  • RAL and finish matching where the product range allows
  • CHAS accredited contractor

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few hours for one area, or a planned series of visits across a bigger building, and we clear our waste as we work. For a building around Grafty Green, 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. First, details come to us: photographs, drawings or a schedule of the areas.
  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. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Warn occupants and staff about the work
  • Point out parking and an unloading spot

Keeping the joints sound

For the best life from the joints:

  • On pre-2000 buildings, share the asbestos information before work starts
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Look at the sealant around anything that has been moved or replaced
  • Make sure ventilation in wet areas is switched on and working

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer. Your maintenance team can look at extract fans at the same time.

Sealant rarely fails all at once across a building. A few splits this year typically mean more next year so the whole run is worth inspecting. We’ll tell you which sealant joints need doing first and which can wait.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Walls or slabs moving more than any sealant can take
  • Misted, cracked or failed glazing units (a glazier’s job)
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think.

What we seal

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