About our mastic sealing in Dragons Green

We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. If you have draught complaints from residents or tenants and repeated reactive repairs to the same buildings, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Dragons Green, preparation and product choice get the time they need.

Around smaller places like Dragons Green, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Mastic sealing in Dragons Green: the local picture

Dragons Green is about 37 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Dragons Green is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

If you’re responsible for a building such as The Church of St Mary the Virgin, frame and door mastic needs the same attention as any other property. For a school such as Shipley CofE Primary School, perimeter mastic on windows and doors is a holiday job.

Dragons Green is about 5 miles south-west of Horsham, in West Sussex. Anywhere in RH13, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our West Sussex coverage takes in 373 places, large and small. Sites around Brighton have their own page, about 16 miles away.

Work on mastic joints is covered throughout RH13. Streets here include Dragons Lane and Dragons Green Road. Close to Dragons Green, our area also takes in Shipley (1 mile south), Whitehall (1 mile south), Broomer's Corner (2 miles south-west), Dial Post (3 miles south) and West Grinstead (3 miles south-east). Bigger towns within reach include Crawley (11 miles north-east), Horsham (5 miles north-east), Worthing (12 miles south), Haywards Heath (12 miles east), Burgess Hill (11 miles east) and Littlehampton (15 miles south-west).

After the work

For the best life from the joints:

  • Protect low-level joints in entrances
  • Avoid piecemeal callouts where you can
  • Have the asbestos survey to hand for older buildings
  • Log resealing dates block by block

Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Why act early in Dragons Green

Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Halls, stores and units around places like Dragons Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Pricing mastic joints depends on quantities, condition and access. Call for a quote.

Your questions answered

Does your area include sites such as Pondtail Farm (Business Park), near Dragons Green?

Yes. Our area takes in Dragons Green and its surroundings, with estates and business parks such as Pondtail Farm (Business Park) included. A few photographs and the unit address let us price the work.

Is Dragons Green off your patch?

Not at all. Dragons Green is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

How many days will you need on site?

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. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

How do you handle work on occupied blocks?

Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Signs you need mastic sealing in Dragons Green

Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.

These are often picked up first by site or facilities staff:

  • Communal area joints that look neglected
  • Leaks at window and door perimeters
  • Complaints coming in block by block
  • Draught complaints from residents or tenants

If you own or manage units on a site such as Pondtail Farm (Business Park), which lies east of Dragons Green, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
