Our commercial sealant contractors service in AL8

Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. The enquiries we see most involve frame mastic that has hardened and come away from the wall and earlier reseals applied straight onto the failed bead, across external facade joints, washrooms and tea points and kitchen worktops and splashbacks.

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself usually taking part of a day on a small job and longer where several buildings or phases are involved.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

What affects the price in AL8

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Quotes

Around Digswell

Around Digswell, our work takes us to commercial buildings near Monk's Walk School, Harwood Hill Junior Mixed Infant and Nursery School and Hedgehog pub. Other local landmarks include Danesbury Park (1.5 miles north-west) and Digswell Village Church (less than half a mile north). There’s a railway station in Digswell itself: Welwyn North station. Nearby you’ll also find Howard Centre (1.3 miles south) and Datchworth Museum (2.6 miles north-east). Green spaces nearby include Tewin Orchard and Hopkyns Wood.

Shops, offices and hotels in AL8

Shop fits, office refurbishments and hotel refits in towns such as Welwyn Garden City, Haldens and Digswell all leave joints that need sealing. Visible joints call for a matched colour and a clean tooled finish.

Around the motorway corridors of the South East, business parks and industrial estates are common, and we cover AL8 along with the rest of the region.

Digswell: Offices and shops close to stations such as Welwyn North station (to the north-east of Digswell) tend to be busy all day, so sealant work is planned around opening hours. Industrial estates such as Little Ridge Industrial Estate, 1.6 miles to the south-east of Digswell, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Owners, agents and contractors

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in AL8 can sit alongside others in a wider programme across Hertfordshire.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep abrasive pads and scrapers off resealed joints
  • Note dates and locations of sealant work for future planning
  • Respect the cure time before reopening an area
  • Look at the sealant around anything that has been moved or replaced

Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces, while a neutral cleaner and a soft cloth do no harm.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, so sound, smooth joints matter.

How the quote is worked out

These are the things that shape the price:

  • Working within restricted access windows
  • Travel to remote or island sites
  • How much there is to seal
  • Induction, permit and paperwork requirements

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

We can often quote from photos and a few details. Please tell us:

  • How the joints are reached, and at what height
  • The asbestos register, for older buildings
  • Your programme or deadline
  • The postcode of the building

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or send photos by email if you’d rather talk the job through.

Why deal with it now?

Sealant is often treated as an afterthought by the trade that fitted the element. Choosing the product, setting the depth and preparing the faces are what a specialist brings. It shows over the following seasons rather than at handover.

What your quote should include

  • Can the work be phased to keep areas open?
  • Their public liability cover
  • How they handle RAMS and site documents
  • How the existing material will be dealt with
