Lower Twydall: questions and answers

Is Lower Twydall too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Does the sea air around Lower Twydall change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

How do you handle work on occupied blocks?

The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

How long does a job like this take?

That varies with the scale of the job, but the work usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.

How do we ask for a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.

What guarantee do you give on resealing?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Mastic sealing in Lower Twydall, done properly

For blocks and buildings in Lower Twydall and across Medway, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. If you’re dealing with patchy repairs in mismatched sealant and cracked, hardened mastic round windows on a block, we can put it right, whatever the surface. For commercial sealant work in Lower Twydall, you deal with one contact from quote to sign-off, whether it’s one building or several.

Owners and agents with buildings around smaller places such as Lower Twydall 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.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Why deal with it now?

Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. Converted and older buildings near places like Lower Twydall tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

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

What you get with us

  • Constructionline member
  • Colour agreed before work starts
  • A range of standard colours, depending on the product
  • Public liability insurance in place

Read what affects the cost and our accreditations and insurance.

What sealant work can’t fix

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

  • Leaks from above rather than through a joint
  • Masonry that has broken away beside the joint
  • Failed window or door frames, which need a window contractor

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.

General trades versus a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Ask residents or tenants to report leaks and draughts early
  • Log resealing dates block by block
  • Group repairs into a planned programme
  • Prioritise elevations facing the weather

Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.

Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Mastic sealing around Lower Twydall: what changes locally

With the shore within about 1 mile, Lower Twydall counts as a coastal location. On buildings near the shore, the side facing the weather typically needs its mastic renewed first, and they deserve more regular inspection. Lower Twydall is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

Churches, halls and community buildings such as Holy Trinity Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Schools and community buildings such as Featherby Infant and Nursery School need frame and external mastic kept sound like any building. If you look after a block within reach of Rainham (Kent) station (1.5 miles south-east of Lower Twydall), frame and balcony mastic can be renewed on one programme.

Lower Twydall is about 1 mile north-east of Gillingham, in Medway. We send applicators to Lower Twydall for mastic joints. Lower Twydall is one of 54 places we cover in Medway. Our London page has more on work in that area (31 miles or so).

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For work around Lower Twydall, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.
