Mastic sealing for commercial buildings in Debden

In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are movement joints with sealant missing and brittle perimeter mastic across a building. Searching for sealant specialists in Debden? We’ve been sealing commercial buildings since 2005.

For owners with a single building near Debden, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Questions we are asked in Debden

Is Debden off your patch?

No. Places such as Debden are covered as much as the big towns. 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 take on block-wide or estate-wide mastic work in Debden?

Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you seal on top of existing sealant?

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

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.

Should maintenance staff do it?

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

What happens if it’s left?

Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure and less choice about when. Converted and older buildings near places like Debden tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Planned mastic for Debden portfolios

At about 36 miles from central London, Debden is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations. Debden sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

Historic properties like Horham Hall (3.1 miles south-east of Debden) show the age of some local stock, where frame mastic must suit soft brick or stone. For a school such as Joyce Frankland Academy, perimeter mastic on windows and doors is a holiday job. Buildings close to stations like Newport (Essex) station, 2.2 miles to the west of Debden, are often flats over shops, with frame mastic to keep sound.

Debden is about 3 miles south of Saffron Walden, in Essex. We cover commercial sites throughout Debden, whether it’s a single job or part of a planned programme. 644 places across Essex fall within our area, Debden among them. We also cover London, some 36 miles away.
