Need construction mastic in Twydall?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What the job involves on each surface

Window and door perimeters

Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification.

Snagging before handover

Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately, depending on what suits the programme.

About our construction mastic in Twydall

On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. If you’re dealing with inconsistent sealant finishes from plot to plot and bath and shower joints scraped during the final clean, we can help. Searching for sealant specialists in Twydall? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

On a small site around Twydall, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Contractors’ notes for Twydall

The sea is no more than about 2 miles from Twydall. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Twydall is in the South East, one of the UK’s drier regions. 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.

Further education sites such as MidKent College Gillingham Campus, 2.3 miles north-west of Twydall, are extended and refurbished from time to time, with mastic often programmed into the summer break. For contractors on a campus like University of Greenwich - Medway, which lies north-west of Twydall, facade and perimeter sealing has to fit around students and term dates. Recladding or extending a unit at a site like Beechings Way Industrial Centre (to the north-west of Twydall) brings panel joints and frame perimeters into the programme.

Twydall is about 1 mile east of Gillingham, in Medway. We cover Twydall and the rest of Medway, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 54 places in Medway. London is covered too, around 31 miles from Twydall.

How the quote is worked out

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

  • The size and state of each joint
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Access and working height

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • Whether an asbestos survey exists
  • Anything awkward about access or site hours
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email us.

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, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If neighbouring businesses or buildings around Twydall need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. First we take quantities off the drawings and read through the specification.
  2. You receive a fixed quote listing scope, products and phasing.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. We close out snagging and hand over with a 12-month guarantee.

Preparing the site

  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use
  • Let building users know which areas are affected

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

FAQs: Twydall

Could you schedule work at a campus like University of Greenwich - Medway 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 Beechings Way Industrial Centre, near Twydall, within your area?

Yes, sites like Beechings Way Industrial Centre are within our area, along with the rest of Twydall. Photos and a short description are enough for a first look.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Can you fit around our programme?

We follow the trades through the building. Areas are sealed as they’re released by the site team, and we will raise anything that holds the work up.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Can you fit around our working hours?

We are 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.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Leave it or put it right?

On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. If the frame is life-expired, we will tell you. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Take a look at what affects the cost and how we’re accredited.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Approving fire stopping as compliant
  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Frames fitted out of tolerance

If in doubt, call the office on 01277 525 020 or email us and we will say what we think.

Surfaces we seal

  • Internal decorators’ caulk
  • Floor and skirting junctions
  • Brick and block movement joints
  • Window and door perimeters
  • Cladding and panel joints
  • Sanitary and kitchen joints
