Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What affects the price in Baker's Cross

These are the things that shape the price:

  • How accessible the joints are
  • The product specified
  • Working within restricted access windows
  • Quantities, in metres or numbers

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • Specification clauses that apply
  • Any dates the work must fit around

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

How we handle facade sealing in Baker's Cross

Facade sealants sit in the sun, rain and frost every day. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. Site teams most often ask us about previous reseals run over old sealant and perimeter joints where frames meet the structure, on perimeter joints where frames meet the structure, cladding panel joints and shopfront frames. Searching for sealant specialists in Baker's Cross? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Conversions of older rural buildings near smaller places such as Baker's Cross bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Baker's Cross 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. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • Let building users know which areas are affected
  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use

When it isn’t the sealant

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

  • Water getting in through cracked render or porous masonry
  • Replacing glass or failed glazing units
  • Damaged frames that need replacing

If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Where we work in Baker's Cross

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

Work for main contractors and building owners

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

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

How the job changes by surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end to the correct depth.

Your questions answered

Would you work within a site like Benenden Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Baker's Cross too far out for you?

Not at all. Baker's Cross is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you just go over the old sealant?

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

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Are you CHAS accredited?

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

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

Leave it or put it right?

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. One visit to deal with every failing joint makes more sense than several trips to a place like Baker's Cross. Photos of every joint help us quote for the whole job.

A quote for facade joints depends on quantities, condition and access. Ask us for a fixed quote.

Why us?

  • Coloured sealants to suit the setting, where available
  • Matching to RAL references, product permitting
  • Joints cleaned back to sound surfaces
  • Constructionline member for supplier checks

Facade sealing in Baker's Cross: the local picture

A number of hotels sit less than 2 miles from Baker's Cross. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Baker's Cross lies roughly 39 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.

School extensions, at buildings such as Cranbrook School, normally run to the summer holidays, mastic included. Units on estates such as Hartley Dyke Business Centre (1.4 miles south-west of Baker's Cross) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Extensions at sites like Benenden Hospital, 3.3 miles to the east of Baker's Cross, typically sit beside working departments, and the mastic follows strict access rules.

Baker's Cross is about 9 miles south-east of Paddock Wood, in Kent. We cover commercial sites throughout Baker's Cross, whether it’s a single job or part of a planned programme. 931 places across Kent fall within our area, including Baker's Cross.
