Facade sealing across Hadham Ford

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Why deal with it now?

Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. For buildings around smaller places like Hadham Ford, 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.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

How we handle facade sealing in Hadham Ford

Managing agents and owners in Hadham Ford ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. If you are dealing with new sealant peeling off old mastic and gaps between rainscreen or cladding panels, we can put it right, whatever the surface. Searching for sealant specialists in Hadham Ford? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Conversions of older rural buildings near smaller places such as Hadham Ford bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Hadham Ford may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  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. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Agree which areas must stay open
  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints

Advice

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Contractors’ notes for Hadham Ford

At about 27 miles from central London, Hadham Ford is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Hadham Ford sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

Historic houses such as Much Hadham Palace (to the south of Hadham Ford) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When units on a site such as Hadham Industrial Estate (to the north-east of Hadham Ford) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Projects at schools like Little Hadham Primary School work to term dates, so mastic is programmed tightly.

Your questions answered

Is a smaller place like Hadham Ford outside your area?

No. Places such as Hadham Ford 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.

Do you take on work at healthcare sites like Herts and Essex Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

What do you charge?

Each job is quoted on its own details. For yours, ring 01277 525 020 or email the details over with a description of the work.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, and we’ll ask to see it. Suspect material is left alone until it has been tested.

Can you just add new sealant on top?

No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

What the job involves on each surface

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints rather than the system it surrounds.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Damp caused by condensation inside the building
  • Specialist high-level access methods
  • Joints whose design needs changing by the specifier

If you are not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer.
