Facade sealing for Bitterne sites

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

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Brief window cleaners about newly sealed joints
  • Note when each elevation was last resealed
  • Confirm the survey covers external sealants in older buildings
  • Add perimeter sealant to planned maintenance checks

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in instead of after the damage.

How we handle facade sealing in Bitterne

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. We work on shopfront frames, stone and brick facade joints and window and door perimeters, and the failures we are asked to look at most are perimeter sealant that has split or peeled away and leaks at window and door perimeters. Searching for sealant specialists in Bitterne? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

In a smaller place such as Bitterne, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.

Brick and stone facades

Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, with masked edges for a clean line.

What we’re called out for in Bitterne

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

Look out for the following:

  • Previous reseals run over old sealant
  • Cladding panel joints that have opened up
  • Perimeter joints where frames meet the structure
  • Cold air coming in at window perimeters

Hotels like Bitterne Park Hotel (0.9 miles north-west of Bitterne) rarely close for long, so refurbishment mastic is phased floor by floor.

  • Proof of insurance

Facades, frames and programmes in Bitterne

With the shore within about 2 miles, Bitterne counts as a coastal location. 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. Bitterne lies roughly 68 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

Further education sites such as Itchen College, under half a mile to the south-east of Bitterne, are extended and refurbished from time to time, with mastic often programmed into the summer break. New wings at hospitals like Royal South Hants Hospital, 1.6 miles west of Bitterne, bring long runs of window and panel joints to seal.

FAQs: Bitterne

Is a hospital such as Royal South Hants Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Bitterne outside your area?

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.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Do you use silicone for external joints?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Is old mastic on our building likely to contain asbestos?

In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed. Removal of asbestos isn’t something we do.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Arranging specialist high-level access, which is planned with the client
  • Damaged frames that need replacing
  • Installing or repairing glazing systems

If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.

Where we work in Bitterne
