Mastic sealing in Leigh Park

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Blocks and managed buildings in Leigh Park

With the shore within about 2 miles, Leigh Park counts as a coastal location. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. Leigh Park lies roughly 58 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.

Historic properties like Warblington Castle (to the south-east of Leigh Park) show the age of some local stock, where frame mastic must suit soft brick or stone. For a school such as Riders Infant School, perimeter mastic on windows and doors is a holiday job.

Leigh Park is about 1 mile north of Havant, in Hampshire. Our applicators travel to Leigh Park for work on mastic joints. We work across 723 places in Hampshire. We also cover Portsmouth, around 6 miles from Leigh Park.

About our mastic sealing in Leigh Park

For blocks and buildings in Leigh Park and across Hampshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. If you have damp patches beside frames and worn sealant at communal door frames, we can put it right. Facilities teams, main contractors and managing agents in Leigh Park tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Owners with buildings around smaller places like Leigh Park often group mastic work so one visit covers several properties. Send the addresses and photographs and we will quote for all of them together.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Misted or failed double-glazed units
  • Water coming in from the roof or rainwater goods
  • Masonry that has broken away beside the joint

If you are not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer.

What we seal

  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • Window and door perimeters on blocks
  • Communal kitchens and washrooms
  • External wall and movement joints
  • Balcony and threshold joints

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Common problems we fix in Leigh Park

Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified it comes away from one face.

Things that typically lead to an enquiry:

  • Old repairs sealed over failed mastic
  • Mastic failing across several blocks on an estate
  • Movement joints with sealant missing
  • Repeated reactive repairs to the same buildings

Buildings close to stations like Havant station (to the south of Leigh Park) are often flats over shops, with frame mastic to keep sound.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Whether their applicators hold CSCS cards
  • How they’ll work around occupants
  • How joint depth will be controlled

How to choose a sealant contractor

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For a job in Leigh Park, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Before we start on site

  • Make sure the joints can be reached
  • Share your working hours and any access restrictions
  • Let building users know which areas are affected

Different surfaces, different methods

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and spreads the work.

External movement joints

Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.

Your questions answered

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

Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.

Can you work at a site such as Dunsbury Hill Business Park, by Leigh Park?

Yes, sites like Dunsbury Hill Business Park are within our area, along with the rest of Leigh Park. Send details of the unit and the work through our quote form for a quick quote.

Can you plan resealing across several buildings?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

How many days will you need on site?

That varies with the scale of the job, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.

Do you cover Leigh Park?

Yes. Leigh Park is in our area and the rest of Hampshire. To discuss a job, speak to us on 01277 525 020 or email us.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
