Hoe Gate: questions and answers

We manage a building near Portchester station. Can you help?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Is Parklands Business Park, near Hoe Gate, within your area?

Yes. Estates, retail parks and business parks around Hoe Gate, Parklands Business Park among them, are all within reach. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

Do you work with property factors and landlords?

Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Mastic sealing in Hoe Gate

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. The enquiries we see most involve patchy repairs in mismatched sealant and complaints coming in block by block, on balcony and threshold joints, communal kitchens and washrooms and external wall and movement joints. For commercial sealant work in Hoe Gate, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places like Hoe Gate, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Looking after buildings in and around Hoe Gate

Hoe Gate lies roughly 60 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Hoe Gate included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

Blocks of flats and mixed-use buildings often cluster around stations such as Portchester station, 4.5 miles south of Hoe Gate, and their window and balcony mastic tends to age at the same rate across a building. Trustees of buildings like Church of the Holy Trinity can bring frame and external mastic into a planned maintenance list.

Hoe Gate is about 4 miles north-west of Waterlooville, in Hampshire. Our applicators travel to Hoe Gate for work on mastic joints. We work across 723 places in Hampshire. We also cover Portsmouth, around 7 miles from Hoe Gate.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Protect low-level joints in entrances
  • Group repairs into a planned programme
  • Share your contractor requirements early
  • Check sealant joints during planned building inspections

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint usually 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.

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Hoe Gate may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Tell us what induction or permit system the site runs
  • Warn occupants and staff about the work

Advice

Commercial clients in Hoe Gate

If you look after buildings for someone else, 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.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

When to call us in Hoe Gate

Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and splits as the building moves.

Typical triggers for a call:

  • Mastic failing across several blocks on an estate
  • Patchy repairs in mismatched sealant
  • Water getting in round frames after rain
  • Damaged joints in communal entrances and corridors

Landlords with units on estates such as Parklands Business Park (to the south-east of Hoe Gate) can bring frame, door and external mastic across several units into one programme.

What to look for in a quote

  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Proof of insurance
  • Can the work be phased to keep areas open?

Our contractor checklist

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Substrate edges that need repairing first
  • Leaks through the frame itself rather than the perimeter
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
