Facade sealing in Hunton, done properly

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. We work on shopfront frames, stone and brick facade joints and perimeter joints where frames meet the structure, and what we are called in for most is gaps between rainscreen or cladding panels and old perimeter mastic that has dried out. Searching for sealant specialists in Hunton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

In the countryside around places like Hunton, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Facade sealing around Hunton: what changes locally

Hunton is about 58 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. A 2-mile radius around Hunton takes in several hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.

Hotels like Norton Park Hotel (to the north-west of Hunton) rarely close for long, so refurbishment mastic is phased floor by floor. Sites around Hunton get mastic sealed to the drawings and the programme, nothing improvised.

Hunton is about 7 miles north of Winchester, in Hampshire. Anywhere in SO21, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Hunton is one of 723 places in Hampshire on our list for facade joints. Our Southampton page has more on work in that area.

Postcode districts covered here: SO21 for facade joints. Nearby places we also cover include Stoke Charity (1 mile south-east), Egypt (1 mile west), Sutton Scotney (1 mile west), South Wonston (3 miles south) and Barton Stacey (3 miles west).

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • The product specified
  • How much existing material needs removing
  • Phasing around occupants
  • Travel to remote or island sites

Pricing facade joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Details that help us quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • What the building is and how it’s used
  • Specification clauses that apply
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to ring 01277 525 020 or email us.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. If others near Hunton need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Explain the parking and delivery arrangements
  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Avoid harsh cleaners on facade sealant
  • Combine resealing with other works that need access
  • Check the asbestos register before old mastic is disturbed
  • Insist on a full cut-out when joints are renewed

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Questions we are asked in Hunton

Can you work to our programme on a site in or near Hunton?

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

What documents will you need to give us for a job in Hunton?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Can the building stay open while you work?

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

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Site staff or a sealant specialist?

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Leave it or put it right?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. For buildings around smaller places like Hunton, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Joints too narrow for the movement they take, which need redesign
  • Arranging specialist high-level access, which is planned with the client
  • Installing or repairing glazing systems

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Joints and surfaces we work on
