Aftercare for building managers

After handover, a little attention goes a long way:

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Add sealant to the planned maintenance inspection list
  • Act on the first lifting edges rather than waiting
  • Keep washroom and kitchen extraction working

Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early. If anything looks wrong, speak to us on 01277 525 020 or email drawings and photos with a photo.

A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

Sealant applicators in Heart's Delight

Most of the buildings we seal stay open while we are there. Tell us your site hours and access windows and we will plan around them. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on washrooms and tea points, floor and threshold joints and window and door perimeters, and the usual reasons a site gets in touch are water staining near frames, panels or ceilings and weathered facade sealant that no longer flexes. Facilities teams, main contractors and managing agents in Heart's Delight tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

The most common commercial job in Heart's Delight is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

In and around smaller places such as Heart's Delight, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Heart's Delight, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First, details reach us through the quote form or 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. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Your questions answered

Is a smaller place like Heart's Delight outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you cover business parks and estates near Heart's Delight, such as Kent Science Park?

Yes. Estates, retail parks and business parks around Heart's Delight, Kent Science Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

How many days will you need on site?

It depends on the scope, but the work usually takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we will set out a timescale with the quote.

What about asbestos in old mastic?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder and removing it isn’t something we do.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Do you work directly for building managers?

Yes. You can send details through our quote form.

Commercial premises in Heart's Delight

The area within 2 miles of Heart's Delight holds a number of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, with rooms done in turn while the rest stay let. Less than 3 miles from Heart's Delight there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.

In hotels such as The Bull Hotel, 1.3 miles north-east of Heart's Delight, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Shops and cafés around stations like Sittingbourne station, 1.4 miles to the north-east of Heart's Delight, trade from early, so work is timed around them.

Heart's Delight is about 1 mile south-west of Sittingbourne, in Kent. We cover commercial sites throughout Heart's Delight. Our Kent coverage takes in 931 places. There’s a separate page for London, about 37 miles away.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Different surfaces, different methods

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.

Why deal with it now?

Sealant is often treated as an afterthought by the trade that fitted the element. Choosing the product, setting the depth and preparing the faces are what a specialist brings. You notice the difference years later, not on the day. Converted and older buildings near places like Heart's Delight tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

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 and we’ll explain how it’s made up.

What we are called out for in Heart's Delight

The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

Common reasons buildings call us in:

  • Wall and floor joints that have lost their seal
  • Frame sealant that has cracked, shrunk or pulled away
  • Gaps behind commercial kitchen worktops and sinks
  • Layers of sealant, all of them failing

On a business park such as Kent Science Park (1.3 miles south-east of Heart's Delight), sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.
