Facade sealing for Loose sites

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

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Loose are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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 both faces cleaned back.
  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.

Preparing the site

  • Explain the parking and delivery arrangements
  • Send your site hours and access windows
  • Tell us which areas need to stay in use

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or send photos by email.

Facade sealing in Loose

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on window and door perimeters, coping and flashing joints and perimeter joints where frames meet the structure, and what we’re called in for most is hard, chalky sealant that no longer flexes and weathered joints at frame-to-structure perimeters. For commercial sealant work in Loose, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places like Loose, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Your questions answered

Does your area include sites such as Tovil Green Business Park, near Loose?

Yes. Our area takes in Loose and its surroundings, with estates and business parks such as Tovil Green Business Park included. A few photographs and the unit address let us price the work.

Is a hospital such as The Somerfield Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all.

Do you work in Loose?

Yes. We take on work across Loose, and the same phone number covers every area.

Do you hold CHAS accreditation?

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

Owners, agents and contractors

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Common problems we fix in Loose

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Clients usually get in touch after noticing one or more of the following:

  • New sealant peeling off old mastic
  • Leaks at window and door perimeters
  • Perimeter sealant that has split or peeled away
  • Cladding panel joints that have opened up

Further education sites such as Kent Police College (to the east of Loose) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • What the guarantee covers, and for how long
  • Their pre-qualification and accreditations
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Damp caused by condensation inside the building
  • Providing access systems for the work
  • Render or concrete edges that have broken away

If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think before you book.

Building and refurbishing in Loose

Loose sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. At about 32 miles from central London, Loose is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

For contractors at a school such as Loose Primary School, sealing has to be finished before term starts. Building work at universities like University for the Creative Arts - Maidstone (to the north of Loose) is often timed for the summer, mastic included.

Loose is about 2 miles south of Maidstone, in Kent. We cover commercial sites throughout Loose. Our Kent coverage takes in 931 places, large and small. Our London page has more on work in that area (32 miles or so).

Anyone looking for facade sealing in ME15 and ME17 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Rosemount Close, Malthouse Hill and Old Loose Hill. Close to Loose, our area also takes in Boughton Green (1 mile south-east), Boughton Monchelsea (1 mile south-east), Linton (1 mile south), Park Wood (2 miles east) and Shepway (2 miles north-east). Nearby towns on our patch include Sittingbourne (12 miles north-east), Sevenoaks (15 miles west), Royal Tunbridge Wells (13 miles south-west), Gravesend (15 miles north-west), Tonbridge (11 miles west) and Northfleet (15 miles north-west).

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Joint width, depth and condition
  • Phasing around occupants
  • Removal of failed or old sealant
  • How accessible the joints are

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Send us:

  • Any dates the work must fit around
  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, give us a call on 01277 525 020 or email the details over.

Doing it in-house

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.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
