Mastic sealing across Springhead

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

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Share the asbestos register when you send details
  • Make mastic part of routine maintenance checks
  • Share your contractor requirements early
  • Log resealing dates block by block

If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.

Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.

Mastic sealing in Springhead

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you have a mix of products and colours from past repairs and repeated reactive repairs to the same buildings, we can put it right. A single leaking joint is often how a building in Springhead first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Owners with buildings around smaller places like Springhead often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Mastic sealing in Springhead: the local picture

Springhead sits close to the coast, within about 3 miles. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.

Property owners at sites such as Ebbsfleet Business Park, 1.2 miles north of Springhead, can have mastic renewed between lettings. Owners of student blocks near University of Greenwich, 2.7 miles west of Springhead, can schedule frame and external mastic for the summer vacation.

Springhead is about 1 mile west of Northfleet, in Kent. Anywhere in DA11, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Kent coverage takes in 931 places, from busy centres to rural villages. London is covered too, around 19 miles from Springhead.

Business premises anywhere in DA11, DA10 and DA13 are within our area. Among the streets we cover are Gwynn Road, Fleet Road and Roman Road, and sites on any of them can send details for a fixed quote.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a site in Springhead, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Make sure the joints can be reached

Quotes

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Doing it in-house

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 most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Your questions answered

Does the sea air around Springhead change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Does your area include sites such as Ebbsfleet Business Park, near Springhead?

Yes. Estates, retail parks and business parks around Springhead, Ebbsfleet Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can you send RAMS and CSCS details before starting?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Can you take on resealing for a block portfolio?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

Can you reseal a whole block or estate?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

Can people stay in the building while you reseal?

The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.

How do you reach windows on upper floors?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.

What we’re called out for in Springhead

Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.

Most enquiries start with one or more of the following:

  • Occupiers reporting cold air round windows
  • Communal area joints that look neglected
  • A mix of products and colours from past repairs
  • Water getting in round frames after rain

Older community buildings, Parish Church of St Botolph among them, often have frames of mixed ages whose mastic varies.

What to look for in a quote

  • Do they follow the manufacturer’s priming guidance?
  • How joint depth will be controlled
  • What the guarantee covers, and for how long
  • Their public liability cover

Our contractor checklist

Quoting for work in Springhead

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Location, for remote and island sites
  • Backing rod, priming and other preparation
  • Phasing around occupants
  • How much there is to seal

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Drawings or a marked-up plan, if available
  • The site address and postcode
  • Specification clauses that apply
  • Your programme or deadline

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email a schedule or drawings with what you know.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Misted or failed double-glazed units
  • Asbestos-containing sealant, which we don’t remove
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
