Mastic sealing for businesses in Ossemsley

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

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Broken glass or failed sealed units
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Failed window or door frames, which need a window contractor

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly.

Joints and surfaces we work on

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

How we handle mastic sealing in Ossemsley

For blocks and buildings in Ossemsley 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 photos and approximate joint numbers are enough for a quick quote or we can visit. We work on window and door perimeters on blocks, external wall and movement joints and shopfronts below residential blocks, and the failures we’re asked to look at most are water getting in round frames after rain and window mastic that has split and shrunk. Looking for mastic applicators who cover Ossemsley? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around smaller places like Ossemsley, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. If others near Ossemsley need work, visits can be combined. A fixed quote is given before anything starts.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Before we start on site

  • Arrange parking or a loading space
  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or use the quote form.

Advice

Questions we’re asked in Ossemsley

Can you work at a site such as Gore Road Industrial Estate, by Ossemsley?

Yes. Our area takes in Ossemsley and its surroundings, with estates and business parks such as Gore Road Industrial Estate included. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is Ossemsley too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

Can you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

Will residents or tenants be disturbed?

We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

Mastic sealing around Ossemsley: how the place shapes the job

Ossemsley is within about 3 miles of the coast. On buildings near the shore, the side facing the weather normally needs its mastic renewed first; plan inspections around that. Ossemsley sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

Schools and community buildings such as Ballard School need frame and external mastic kept sound like any building. Churches, halls and community buildings such as St John are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Ossemsley is about 2 miles north of New Milton, in Hampshire. We cover Ossemsley and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. Our Hampshire coverage takes in 723 places. There’s a separate page for Southampton, roughly 15 miles from Ossemsley.

We also cover Bashley (1 mile south-east), Wootton (1 mile north), Tiptoe (2 miles east), Mead End (2 miles east) and Ashley (2 miles south-east) for mastic joints.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Which sealant the job calls for
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements
  • Joint width, depth and condition

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Whether an asbestos survey exists
  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • Any specification or named product

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

How the job changes by surface

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent.

External movement joints

The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Do you need mastic sealing in Ossemsley?

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

Most enquiries start with one or more of the following:

  • Damp patches beside frames
  • Occupiers reporting cold air round windows
  • Complaints coming in block by block
  • Estate-wide sealant that is simply worn out

Landlords with units on estates such as Gore Road Industrial Estate (to the south of Ossemsley) can bring frame, door and external mastic across several units into one programme.

  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
