Mastic packages on Over Norton sites

Over Norton is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. There are a number of hotels within about 2 miles of Over Norton. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.

Historic houses such as Chastleton House (to the west of Over Norton) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. New units and refits on sites such as London Road Retail Park, 0.7 miles to the south-east of Over Norton, need their panel and perimeter joints sealed to the specification.

About our facade sealing in Over Norton

Managing agents and owners in Over Norton ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. If you have weathered joints at frame-to-structure perimeters and cladding panel joints that have opened up, we can help, whatever the surface. Looking for mastic applicators who cover Over Norton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Sites around smaller places like Over Norton can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For work around Over Norton, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  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. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • Share the asbestos register for older buildings
  • Arrange parking or a loading space
  • Agree which areas must stay open

Ask for a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email drawings and photos.

Related advice

Signs you need facade sealing in Over Norton

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.

Look out for the following:

  • Sealant pulling away from frames or panels
  • Hard, chalky sealant that no longer flexes
  • Patch repairs that keep failing
  • Damp patches beside frames after rain

For contractors at a school such as Holy Trinity Catholic School, sealing has to be finished before term starts.

What to look for in a quote

  • The named product and why it was chosen
  • Health and safety accreditation such as CHAS
  • Whether primer will be used where the manufacturer specifies it
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

Different surfaces, different methods

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.

General trades versus a 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. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Building owners, agents and FMs in Over Norton

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Work on the window or framing system itself
  • Movement beyond what any sealant can handle
  • Providing access systems for the work

If you are not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.

What we seal

  • Window and door perimeters
  • Coping and flashing joints
  • Stone and brick facade joints
  • Perimeter joints where frames meet the structure
  • Cladding panel joints
  • Shopfront frames

Questions about Over Norton

Does your area include sites such as London Road Retail Park, near Over Norton?

Yes. We cover Over Norton and the area around it, including industrial estates, business parks and retail parks such as London Road Retail Park. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is Over Norton too small for you to travel to?

Not at all. Over Norton is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months on every job.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Is old mastic on our building likely to contain asbestos?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, and we’ll ask to see it. If asbestos is suspected, work stops until it is tested.

Can you just add new sealant on top?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
