Facade sealing near Howe Street

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

Do you need facade sealing in Howe Street?

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

These are often picked up first by site or facilities staff:

  • New sealant peeling off old mastic
  • Gaps between rainscreen or cladding panels
  • Discoloured or dirty facade joints
  • Cold air coming in at window perimeters

On a healthcare site such as Broomfield Hospital, 2 miles south of Howe Street, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Before you book anyone

  • Health and safety accreditation such as CHAS
  • How they handle RAMS and site documents
  • How the joint faces will be prepared and primed
  • The terms of the workmanship guarantee

Our contractor checklist

Facade sealing in Howe Street, done properly

Facade sealants sit in the sun, rain and frost every day. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. Site teams most often ask us about cladding panel joints that have opened up and hard, chalky sealant that no longer flexes, on perimeter joints where frames meet the structure, shopfront frames and window and door perimeters. Most enquiries from Howe Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a site near Howe Street, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Mastic packages on Howe Street sites

Rainfall across the South East, Howe Street included, is lower than in many 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. Howe Street lies roughly 32 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

University estates such as Anglia Ruskin University (to the south of Howe Street) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When units on a site such as Regiment Business Park (to the south-east of Howe Street) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Howe Street is about 5 miles north of Chelmsford, in Essex. Howe Street sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 644 places across Essex fall within our area, including Howe Street. We also cover London, some 32 miles away.

Questions we’re asked in Howe Street

Is Howe Street too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is Regiment Business Park, near Howe Street, within your area?

Yes. Estates, retail parks and business parks around Howe Street, Regiment Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Are you CHAS accredited and on Constructionline?

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

Do you seal on top of existing sealant?

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

Is it okay to overlay old mastic?

No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.

Should maintenance staff do it?

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Leave it or put it right?

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice. Older rural buildings around Howe Street move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Record the product and colour used on each elevation
  • Keep sills, gutters and drainage paths clear
  • Add perimeter sealant to planned maintenance checks
  • Never let anyone seal over old sealant

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.

Commercial clients in Howe Street

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Smaller jobs around Howe Street can be grouped with others nearby. A fixed quote is given before anything starts.

  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 and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Tell us which areas need to stay in use
  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed
