Facade sealing for Parker's Green sites

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

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Smaller jobs around Parker's Green can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

Advice

About our facade sealing in Parker's Green

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. We work on coping and flashing joints, perimeter joints where frames meet the structure and window and door perimeters, and what we’re called in for most is perimeter sealant that has split or peeled away and perimeter joints where frames meet the structure. One point of contact handles commercial sealant work in Parker's Green from the first photos to the final walk-round, whether it’s one building or several.

Construction in and around smaller places such as Parker's Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

The 12-month guarantee is for workmanship rather than 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

Can you work on a hospital site such as Hollanden Park Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Could you schedule work at a campus like University of Kent - Tonbridge for the vacation?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Parker's Green in your area?

Yes. Parker's Green is in our area and the rest of Kent. For a quote, phone 01277 525 020 or use the quote form.

Do you replace windows or glass?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

What hours do you work?

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

How long does a job like this take?

That varies with the scale of the job, though a typical visit typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Are you CHAS accredited and on Constructionline?

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

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

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

What sets the cost

The price varies from site to site. Expect it to depend on:

  • The total length or number of joints
  • Removal of failed or old sealant
  • The site’s rules and procedures
  • How accessible the joints are

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height
  • Your programme or deadline
  • The product your specification calls for

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Report water ingress at frames as soon as it shows
  • Plan facade sealing alongside redecoration
  • Insist on a full cut-out when joints are renewed
  • Check the asbestos register before old mastic is disturbed

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in instead of after the damage.

Building and refurbishing in Parker's Green

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Parker's Green lies roughly 26 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

For contractors on a campus like University of Kent - Tonbridge (2.3 miles south-west of Parker's Green), facade and perimeter sealing has to fit around students and term dates. When a college such as Hadlow College (1.1 miles north-east of Parker's Green) builds or refurbishes, the mastic package usually has to fit around students and staff. Projects at schools like Woodlands Primary School work to term dates, so mastic is programmed tightly.

Parker's Green is about 2 miles north-east of Tonbridge, in Kent. Parker's Green sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Installing or repairing glazing systems
  • Providing access systems for the work
  • Movement beyond what any sealant can handle

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.

What we seal

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

How the job changes by surface

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
