How we handle facade sealing in North Holmwood

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters. We work on coping and flashing joints, shopfront frames and stone and brick facade joints, and the failures we are asked to look at most are weathered facade joints that have lost their grip and sealant pulling away from frames or panels. Looking for mastic applicators who cover North Holmwood? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Building work in places the size of North Holmwood is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

A 12-month guarantee applies to all our work in Surrey. Should something we installed fail, speak to us on 01277 525 020 or email the details over and we will come back to it.

Signs you need facade sealing in North Holmwood

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Things that usually lead to an enquiry:

  • Discoloured or dirty facade joints
  • Patch repairs that keep failing
  • Gaps between rainscreen or cladding panels
  • Facade joints cracked through the middle

New units and refits on sites such as Glebelands Centre Business Park (to the north-west of North Holmwood) need their panel and perimeter joints sealed to the specification.

How to choose a sealant contractor

Building and refurbishing in North Holmwood

A number of hotels sit less than 2 miles from North Holmwood. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. North Holmwood lies roughly 22 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

For a contractor at a hotel such as The Bell Hotel, which lies north of North Holmwood, the mastic often has to be finished before a reopening date. When a school such as St John's Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

North Holmwood is about 1 mile south of Dorking, in Surrey. We cover North Holmwood and the rest of Surrey, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

Diagnose, treat, 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 we move to the next. Work in places the size of North Holmwood is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Tell us which areas need to stay in use
  • Let us know about inductions and permits

Surface by surface

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair first.

What we can’t put right

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

  • Providing access systems for the work
  • Work on the window or framing system itself
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

What we seal

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

Why it’s worth doing now in North Holmwood

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why choose Mastic Doctor in North Holmwood

  • Clear, fixed quotes
  • 12 months’ guarantee on every job
  • RAL and finish matching where the product range allows
  • Old sealant cut out, never sealed over

Your questions answered

Do you take on work at healthcare sites like Dorking Community Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is North Holmwood too small for you to travel to?

No. Places such as North Holmwood are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Do you seal facades in winter?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, and we build that into the programme.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Can you look at water coming in around a frame?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Cost factors for facade joints

Quotes vary with the job. Expect it to depend on:

  • The product specified
  • Phasing around occupants
  • The size and state of each joint
  • Removal of failed or old sealant

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.

Details that help us quote

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

  • Any specification or named product
  • How the joints are reached, and at what height
  • Clear photos of the problem areas
  • Your programme or deadline

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or send photos by email to discuss it first.
