Mastic sealing for businesses in Hawley

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Mastic sealing in Hawley, done properly

Managing agents and housing associations typically need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. If you’re dealing with draughts at frames across a block and open joints in brickwork or panels, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hawley it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Your questions answered

Do you work for managing agents with blocks near Farningham Road station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Is Dartford Heath Retail Park, near Hawley, within your area?

Yes. Estates, retail parks and business parks around Hawley, Dartford Heath Retail Park among them, are all within reach. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

How many days will you need on site?

It depends on the scope, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

What the job involves on each surface

Tenement and older buildings

Traditional buildings have joints that need a careful approach. We look at the substrate before choosing a sealant.

External movement joints

External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Protect low-level joints in entrances
  • Track which buildings were done and when
  • Start inspections with the most exposed faces
  • Include mastic in your cyclical inspections

If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

For managing agents and facilities managers

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

We work for building owners and managing agents on everything from one building to a spread of sites around Hawley. One quote can cover more than one site, which keeps the paperwork simple.

Frames, entrances and external joints in Hawley

Hawley sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Hawley is about 15 miles from central London. Managed blocks of flats are a big part of commuter-belt property.

Property owners at sites such as Dartford Heath Retail Park (1.5 miles north-west of Hawley) can have mastic renewed between lettings. If your remit includes a building such as Sutton-At-Hone Church of England Primary School, frame and door mastic can be programmed for the holidays. For agents with blocks near Farningham Road station, 1.5 miles to the south of Hawley, a block-wide mastic programme deals with frames, balconies and entrances in one go.

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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Leave it or put it right?

Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work with less control over timing. One visit to deal with every failing joint makes more sense than several trips to a place like Hawley, rather than one at a time. Send photos of each area and we will quote for the lot.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
