Mastic sealing in Hambledon, done properly

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you have communal area joints that look neglected and a mix of products and colours from past repairs, we can help. One point of contact handles commercial sealant work in Hambledon from the first photos to the final walk-round, whether it’s one building or several.

Owners and agents with buildings around smaller places such as Hambledon tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

FAQs: Hambledon

Can you work at a site such as Parklands Business Park, by Hambledon?

Yes, sites like Parklands Business Park are within our area, along with the rest of Hambledon. A few photos and the unit address let us price the work.

Can one quote cover a number of our buildings near Hambledon?

Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.

Do you cover Hambledon?

Yes. Hambledon is in our area. For a quote, phone 01277 525 020 or send details through our quote form.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What if the old mastic contains asbestos?

Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

How do you reach windows on upper floors?

It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Can you send RAMS and CSCS details before starting?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Hambledon, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  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

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • Share your working hours and any access restrictions

Request a quote

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.

Cost factors for mastic joints

Quotes vary with the job. It mainly depends on:

  • How much there is to seal
  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages

A quote for mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Before you send an enquiry

We can often quote from photos and a few details. Please tell us:

  • Whether the building will be occupied during the work
  • Clear photographs of the problem areas
  • Access details, including height
  • Asbestos survey details if the building is older

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Failed window or door frames, which need a window contractor
  • Broken glass or failed sealed units
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If you’re not sure, just ring 01277 525 020 or use the quote form and we’ll give you a straight answer.

Surfaces we seal

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

Aftercare for building managers

For the best life from the joints:

  • Reduce knocks to communal area joints
  • Encourage occupiers to report problems at frames
  • Share the asbestos register when you send details
  • Track which buildings were done and when

Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.

One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

For owners and agents in Hambledon

The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first. At about 58 miles from central London, Hambledon is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

Landlords with units on estates such as Parklands Business Park, 2.5 miles south of Hambledon, can bring frame, door and external mastic across several units into one programme. For a school such as Hambledon Primary School, perimeter mastic on windows and doors is a holiday job.

Hambledon is about 4 miles north-west of Horndean, in Hampshire. Hambledon sits inside our coverage and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else.

How the job changes by surface

Planned maintenance

Planned resealing replaces emergency callouts and keeps budgets predictable.

Commercial and mixed-use buildings

Mixed-use buildings combine shops below with flats or offices above the programme has to suit everyone. Tell us your site hours and access windows and we’ll plan around them.

Common problems we fix in Hambledon

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.

Common reasons buildings call us in:

  • Damp patches beside frames
  • A mix of products and colours from past repairs
  • Mastic failing across several blocks on an estate
  • Occupiers reporting cold air round windows

Older community buildings, Church of St Peter and St Paul among them, often have frames of mixed ages whose mastic varies.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Their public liability cover
  • The terms of the workmanship guarantee
  • Will failed sealant be removed rather than covered?
