About our commercial sealant contractors in Hadham Ford

Having a single contact for all your sites makes sealant far simpler to manage.

For sites in Hadham Ford, the quickest start is to give us a call on 01277 525 020 or email us with a list of addresses. If you’re dealing with wall and floor joints that have lost their seal and leaks that seem to come through a sealant line, we can put it right, on movement joints in walls and floors, washrooms and tea points and window and door perimeters alike. A specialist sealant contractor works differently from a general builder: in Hadham Ford, that means joint design, primers and backing rod as standard.

Commercial sealant work around smaller places like Hadham Ford tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Broken glass or blown double-glazed units
  • A failed roof covering or waterproofing membrane
  • Walls or slabs moving more than any sealant can take

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Where we work in Hadham Ford

  • Window and door perimeters
  • External facade joints
  • Kitchen worktops and splashbacks
  • Movement joints in walls and floors
  • Floor and threshold joints
  • Washrooms and tea points

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Make sure ventilation in wet areas is switched on and working
  • On pre-2000 buildings, share the asbestos information before work starts
  • Note dates and locations of sealant work for future planning
  • Add sealant to the planned maintenance inspection list

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.

Sealant rarely fails all at once across a building. A few splits this year usually mean more next year so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.

Do you need commercial sealant contractors in Hadham Ford?

A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath. By the time it shows, there can be two or three layers to cut out.

Look out for the following:

  • Sanitary sealant that has gone black and patchy
  • Damp patches where an external joint has failed
  • A top-up bead over failed sealant, now lifting
  • Expansion joints with the sealant torn out

Trade counters and showrooms on estates such as Hadham Industrial Estate, 1 mile to the north-east of Hadham Ford, need neat joints where customers see them.

Before you book anyone

  • How long is the guarantee, and what does it include?
  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?
  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

Commercial premises in Hadham Ford

The South East is one of the drier parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. The 3 miles around Hadham Ford take in two named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it.

Offices and shops close to stations such as Bishops Stortford station (3.5 miles east of Hadham Ford) tend to be busy all day, so sealant work is planned around opening hours. Sites a few miles apart, such as Hadham Industrial Estate and Standon Business Park, can share one programme and one point of contact.

Hadham Ford: questions and answers

Is Hadham Ford too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you offer colour-matched sealant for buildings in Hadham Ford?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photos and we will confirm what’s available for the product.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Can areas stay open during the work?

That comes down to planning: areas are phased, access windows agreed and enough washrooms or entrances left in use. Tell us what has to stay open and we will plan the job around it.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is it OK to apply fresh sealant over existing beads?

The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.

How the job changes by surface

Window and door perimeters

Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t, matched to the frame colour where colour matters.

Movement joints in walls and floors

Movement joints in walls and floors let the structure expand and contract. Failed seals let grit and water in, and the edges start to suffer. The new sealant is chosen for the movement and, on floors, the traffic.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Hadham Ford, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Tell us which areas need to stay in use
  • Arrange parking or a loading space
  • Send your site hours and access windows
