Looking after buildings in and around Little Hadham

Rainfall across the South East, Little Hadham included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Little Hadham lies roughly 28 miles out from central London. Managed blocks of flats are a big part of commuter-belt property.

If you’re responsible for a building such as Parish Church of St Cecilia, frame and door mastic needs the same attention as any other property. Older buildings near Little Hadham, from historic houses such as Much Hadham Palace (2 miles south of Little Hadham) to more modest stock, need compatible products when frames are resealed.

About our mastic sealing in Little Hadham

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. We work on communal kitchens and washrooms, window and door perimeters on blocks and balcony and threshold joints, and the failures we are asked to look at most are window mastic that has split and shrunk and estate-wide sealant that is simply worn out. Whoever orders the work in Little Hadham, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

For buildings around smaller places like Little Hadham, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Common questions from Little Hadham clients

Does your area include sites such as Hadham Industrial Estate, near Little Hadham?

Yes. Our area takes in Little Hadham and its surroundings, with estates and business parks such as Hadham Industrial Estate included. Photos and a short description are enough for a first look.

Is Little Hadham too far out for you?

No. Places such as Little Hadham are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How long does a job like this take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

On site: what to expect

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes one or more days per building, depending on the joint lengths and the access. Rural sites near Little Hadham may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Before we start on site

  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
  • Tell staff and tenants when we will be in

Advice

Commercial clients in Little Hadham

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Why act early in Little Hadham

Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Halls, stores and units around places like Little Hadham may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • CHAS accredited contractor
  • Our applicators hold CSCS cards
  • One phone line for London, the South East and Scotland
  • Public liability insurance in place

Take a look at what affects the cost or our accreditations and insurance.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Log resealing dates block by block
  • Ask residents or tenants to report leaks and draughts early
  • Check the asbestos register before any old mastic is disturbed
  • Check sealant joints during planned building inspections

If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.

Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Common problems we fix in Little Hadham

Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.

Most enquiries start with something like this:

  • Damp patches beside frames
  • Worn sealant at communal door frames
  • Estate-wide sealant that is simply worn out
  • Occupiers reporting cold air round windows

If you look after a block within reach of Bishops Stortford station, which lies east of Little Hadham, frame and balcony mastic can be renewed on one programme.

Comparing quotes

  • Do they follow the manufacturer’s priming guidance?
  • Which product they’ll use, and why it suits the joint
  • Can the work be phased to keep areas open?
  • Their approach to joint depth and backing

How to choose a sealant contractor

How the job changes by surface

External movement joints

The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.

Window and door perimeters on blocks

Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
