Need facade sealing in Eastrop?

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

Aftercare for building managers

A few simple habits keep the new joints working:

  • Report water ingress at frames as soon as it shows
  • Share access with other external trades
  • Walk the elevations once or twice a year
  • Ask about asbestos in pre-2000 mastic

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade rather than sitting against the joints.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.

Facade sealing in Eastrop, done properly

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. If you have old perimeter mastic that has dried out and perimeter joints where frames meet the structure, we can put it right. A specialist sealant contractor works differently from a general builder: in Eastrop, that means joint design, primers and backing rod as standard.

For a contractor on a smaller site near Eastrop, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Eastrop: questions and answers

Is a smaller place like Eastrop outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you plan work around the academic year at somewhere like Basingstoke College of Technology?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months on every job.

Is it okay to overlay old mastic?

No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What we are called out for in Eastrop

Adhesive failure, where the sealant peels away from one face, normally comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.

Clients typically get in touch after noticing one or more of the following:

  • Staining on stone next to old sealant
  • Weathered facade joints that have lost their grip
  • Failed seals around shopfront and entrance frames
  • Facade joints cracked through the middle

School extensions, at buildings such as The Costello School, usually run to the summer holidays, mastic included.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • The named product and why it was chosen
  • Whether primer will be used where the manufacturer specifies it
  • Will failed sealant be removed rather than covered?

Our contractor checklist

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Water getting in through cracked render or porous masonry
  • Replacing glass or failed glazing units
  • Movement beyond what any sealant can handle

If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Surfaces we seal

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

Facade sealing in Eastrop: the local picture

Rainfall across the South East, Eastrop included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Central London is about 46 miles from Eastrop. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Recladding or extending a unit at a site like Daneshill East Industrial Estate, 1 mile north-east of Eastrop, brings panel joints and frame perimeters into the programme. Hospital estates such as Basingstoke and North Hampshire Hospital (1.7 miles north-west of Eastrop) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Eastrop is about 1 mile east of Basingstoke, in Hampshire. Anywhere in RG21, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, Eastrop among them. For work in that direction, see our Reading page.

We take on facade joints across the RG21 and RG24 postcode area, whatever the building. Buildings on New Road, Vyne Road and Goat Lane are within our area. With the A3010 nearby, Eastrop is easy to get to with materials and equipment. Nearby places we also cover include Oakridge (1 mile north-west), Viables (1 mile south), Lychpit (1 mile east), Popley (1 mile north) and Old Basing (2 miles east). Further afield, our area takes in Farnborough (14 miles east), Fleet (11 miles east), Aldershot (14 miles east), Alton (9 miles south-east), Yateley (12 miles north-east) and Tadley (7 miles north-west).

What the job involves on each surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For a job in Eastrop, the main thing is a clear picture of the work. A fixed quote follows.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Send your site hours and access windows
  • Agree which areas must stay open
  • Let building users know which areas are affected
