Looking after buildings in and around Newenden

Newenden is about 45 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Newenden included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building typically need attention first.

Historic properties like Great Dixter, 1.7 miles to the south-west of Newenden, show the age of some local stock, where frame mastic must suit soft brick or stone. Older community buildings, Parish Church of St Peter among them, often have frames of mixed ages whose mastic varies.

Newenden is about 10 miles north of Hastings, in Kent. Anywhere in TN18, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 931 places across Kent fall within our area, Newenden among them. For work in that direction, see our Brighton page (35 miles or so).

Mastic sealing for commercial buildings in Newenden

For blocks and buildings in Newenden and across Kent, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. If you have water getting in round frames after rain and the same joint failures repeated across a portfolio, we can put it right. A specialist sealant contractor works differently from a general builder: on jobs in Newenden, preparation and product choice get the time they need.

Owners and agents with buildings around smaller places such as Newenden tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Cost factors for mastic joints

The price varies from site to site. It mainly depends on:

  • Access and working height
  • Distance, for remote addresses
  • Phasing around occupants
  • How much existing material needs removing

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • Your programme or deadline
  • Approximate linear metres or a joint schedule
  • What the building is and how it’s used
  • A wide shot and a close-up of the area

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email the details over.

Questions we are asked in Newenden

Can one quote cover a number of our buildings near Newenden?

Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.

Is Newenden off your patch?

Not at all. Newenden is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you guarantee the mastic work?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it.

Can you seal joints high up on a block?

It depends on the building. We agree access with you at quote stage so there are no surprises.

Should maintenance staff do it?

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.

Redoing a failed joint usually costs more than getting it right at the outset, 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.

Why act early in Newenden

Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. One visit to deal with every failing joint makes more sense than several trips to a place like Newenden, rather than one at a time. Photos of every joint help us quote for the whole job.

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.

Owners, agents and contractors

Main contractors use us as their 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.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Honest limits

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

  • Materials that need asbestos testing before work
  • Water coming in from the roof or rainwater goods
  • Substrate edges that need repairing first

If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.

  • External wall and movement joints
  • Communal kitchens and washrooms
