Need mastic sealing in Heath End?

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

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Mastic sealing in Heath End

There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. Most enquiries involve damaged joints in communal entrances and corridors and draughts at frames across a block, across balcony and threshold joints, window and door perimeters on blocks and communal kitchens and washrooms. Most enquiries from Heath End start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Heath End, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

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.

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. Rural sites near Heath End may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Getting the site ready

  • Arrange parking or a loading space
  • Move anything stored against the joints
  • Let building users know which areas are affected

Why it’s worth doing now in Heath End

A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. One visit to deal with every failing joint makes more sense than several trips to a place like Heath End, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Fixed quotes based on photos, drawings or a visit
  • Commercial sealant work since 2005
  • Old sealant cut out, never sealed over
  • Workmanship guaranteed for 12 months

Common questions from Heath End clients

Can you work at a site such as Scion Business Park, by Heath End?

Yes. Estates, retail parks and business parks around Heath End, Scion Business Park among them, are all within reach. To start, just phone 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is a smaller place like Heath End outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What paperwork can you provide?

Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

What’s the quickest route to a quote?

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

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Owners, agents and contractors

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

What we’re called out for in Heath End

Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.

Typical triggers for a call:

  • Failed external movement joints
  • A mix of products and colours from past repairs
  • Damaged joints in communal entrances and corridors
  • Repeated reactive repairs to the same buildings

For agents with blocks near Midgham station, 2.6 miles to the north of Heath End, a block-wide mastic programme deals with frames, balconies and entrances in one go.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Do they follow the manufacturer’s priming guidance?
  • How they’ll work around occupants
  • How joint depth will be controlled

How to choose a sealant contractor

Looking after buildings in and around Heath End

Central London is about 47 miles from Heath End. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, Heath End included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.

For owners of several units at places like Scion Business Park, 0.8 miles to the north-west of Heath End, one programme can deal with frame and external mastic across the lot. If you are responsible for a building such as Saint Mary's Church, frame and door mastic needs the same attention as any other property.
