Mastic sealing for Blindley Heath sites

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

Leave it or put it right?

Draughts round window perimeters cost occupiers comfort and the windows typically get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Converted and older buildings near places like Blindley Heath tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why us?

  • Fully insured
  • CHAS accredited contractor
  • Standard and matched colours in many product ranges
  • Joints cleaned back to sound surfaces

How we handle mastic sealing in Blindley Heath

There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable. We’ll confirm the colours available for the specified product. We work on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints, and the usual reasons a site gets in touch are damaged joints in communal entrances and corridors and draughts at frames across a block. Facilities teams, main contractors and managing agents in Blindley Heath tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Blindley Heath, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What the job involves on each surface

Planned maintenance

Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.

Commercial and mixed-use buildings

Where retail and residential share a building, so phasing has to suit both. Tell us your site hours and access windows and we will plan around them.

Frames, entrances and external joints in Blindley Heath

Blindley Heath lies roughly 21 miles out from central London. Managed blocks of flats are a big part of commuter-belt property. Blindley Heath is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.

For owners of several units at places like Hays Bridge Business Park, 0.9 miles south-west of Blindley Heath, one programme can deal with frame and external mastic across the lot. Churches, halls and community buildings such as Church of St John the Evanglist are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Buildings close to stations like Godstone station, 1.5 miles to the north of Blindley Heath, are often flats over shops, with frame mastic to keep sound.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Putting right a botched joint often costs more than sealing it well at the start, 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.

Questions about Blindley Heath

Is Blindley Heath too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on work at estates like Hays Bridge Business Park, close to Blindley Heath?

Yes. Our area takes in Blindley Heath and its surroundings, with estates and business parks such as Hays Bridge Business Park included. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

What about access for upper-floor joints?

Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.

Can people stay in the building while you reseal?

We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Blindley Heath, 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. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work

  • Broken glass or failed sealed units

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
