Facade sealing in Mortimer

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

Facade sealing for commercial buildings in Mortimer

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around. If you’re dealing with weathered facade joints that have lost their grip and staining on stone next to old sealant, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Mortimer from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Conversions around smaller places like Mortimer often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Site staff or a sealant specialist?

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.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What the job involves on each surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Render or concrete edges that have broken away
  • Specialist high-level access methods
  • Damp caused by condensation inside the building

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly before you book.

What we seal

  • Coping and flashing joints
  • Cladding panel joints
  • Stone and brick facade joints
  • Window and door perimeters
  • Perimeter joints where frames meet the structure
  • Shopfront frames

How the quote is worked out

Before we quote, we look at:

  • The total length or number of joints
  • Which sealant the job calls for
  • Any access equipment needed
  • Removal of failed or old sealant

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

What to include in your enquiry

We can often quote from photographs and a few details. It helps to include:

  • The asbestos register, for older buildings
  • When you need the work done
  • Where the site is, with the postcode
  • What the building is and how it’s used

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, speak to us on 01277 525 020 or use the quote form.

Questions we are asked in Mortimer

Will you fit the mastic around our build programme in Mortimer?

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Does your area include sites such as Stacey Industrial Park, near Mortimer?

Yes. We cover Mortimer and the area around it, including industrial estates, business parks and retail parks such as Stacey Industrial Park. Send details of the unit and the work through our quote form for a quick quote.

Can staff carry on working while you’re here?

In the majority of cases, yes. We phase the work so most of the building stays in use.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you work in Mortimer?

Yes. Sites across Mortimer are covered, and the same phone number covers every area.

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

How a job runs

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 the sealant is tooled off neatly. If neighbouring businesses or buildings around Mortimer need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Send your site hours and access windows
  • Flag any permit to work we will need
  • Confirm the product named in the specification

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Contractors’ notes for Mortimer

Mortimer is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Mortimer lies roughly 43 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

With historic properties like Stratfield Saye House (3.6 miles south-east of Mortimer) in the area, refurbishment work often meets old masonry that needs compatible sealants. Units on estates such as Stacey Industrial Park (to the south-west of Mortimer) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. School extensions, at buildings such as Mortimer St John's C.E. Infant School, usually run to the summer holidays, mastic included.
