Facade sealing in Hazeley

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you have weathered joints at frame-to-structure perimeters and patch repairs that keep failing, we can help, whatever the surface. Searching for sealant specialists in Hazeley? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Construction in and around smaller places such as Hazeley 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.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint typically 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.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Movement beyond what any sealant can handle
  • Specialist high-level access methods
  • Water getting in through cracked render or porous masonry

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly before you book.

Surfaces we seal

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

How a job runs

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 a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. If others near Hazeley need work, visits can be combined. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  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. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use
  • Let us know about inductions and permits

Advice

What the job involves on each surface

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch as the frame moves.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Keep pressure washers away from fresh sealant
  • Check that rainwater leaves the facade the way it was designed to
  • Insist on a full cut-out when joints are renewed
  • Report water ingress at frames as soon as it shows

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade instead of soaking the joints.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.

Why act early in Hazeley

Topping up a failed joint typically buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Converted and older buildings near places like Hazeley tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Questions about Hazeley

Is Hazeley too small for you to travel to?

Not at all. Hazeley is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Fleet Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we will tell you which.

Do you replace failed glazing units?

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

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Facade sealing around Hazeley: points for this area

Hazeley lies roughly 38 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

With historic properties like Stratfield Saye House (to the north-west of Hazeley) in the area, refurbishment work often meets old masonry that needs compatible sealants. On a healthcare site such as Fleet Community Hospital, which lies south-east of Hazeley, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Units on estates such as Brocketts Business Park, 1.7 miles south-east of Hazeley, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Hazeley is about 4 miles west of Yateley, in Hampshire. Commercial clients in Hazeley can call on us for facade joints. 723 places across Hampshire fall within our area, including Hazeley. Our Reading page has more on work in that area, about 8 miles away.
