Your questions answered

Do you take on jobs in Benhilton where loading and access are tightly controlled?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for

Can you work around term dates at a campus such as University for the Creative Arts - Epsom?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Is Benhilton in your area?

Yes. Benhilton is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, call the office on 01277 525 020 or send photos by email.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

How we handle facade sealing in Benhilton

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. If you’re dealing with discoloured or dirty facade joints and previous reseals run over old sealant, we can put it right, on cladding panel joints, shopfront frames and stone and brick facade joints alike. A single leaking joint is often how a building in Benhilton first comes to us: we look at the rest while we’re there and tell you what we find.

Around Benhilton, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Why deal with it now?

Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.

We don’t publish prices, since every building and every scope is different. Call for a quote.

Building owners, agents and FMs in Benhilton

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Benhilton can form part of a wider programme.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. In Benhilton, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

What we need from you

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • Point out parking and an unloading spot

Maintenance after handover

For the best life from the joints:

  • Share access with other external trades
  • Check that rainwater leaves the facade the way it was designed to
  • Note when each elevation was last resealed
  • Avoid patch repairs on failed facade joints

After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.

New build and refits around Benhilton

Several hotels sit less than 2 miles from Benhilton. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. The ULEZ covers the whole of Greater London, Benhilton included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.

New units and refits on sites such as Kimpton Industrial Park (0.7 miles west of Benhilton) need their panel and perimeter joints sealed to the specification. For contractors on a campus like University for the Creative Arts - Epsom, 4.3 miles to the south-west of Benhilton, facade and perimeter sealing has to fit around students and term dates.

Benhilton is about 4 miles south of Wimbledon, in Greater London. Commercial clients in Benhilton can call on us for facade joints. 764 places across Greater London fall within our area, including Benhilton. London is covered too, some 10 miles away.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What we are called out for in Benhilton

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Typical triggers for a call:

  • Facade joints cracked through the middle
  • Failed seals around shopfront and entrance frames
  • Patch repairs that keep failing
  • Draughts around frames and panels

For contractors at a college like Sutton College of Learning for Adults (0.9 miles south of Benhilton), perimeters and internal sealant are timed for the holidays.
