External mastic in Limmo Peninsula

About our external mastic in Limmo Peninsula

As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we do not skip that step. Common call-outs are for rigid filler in a joint that should flex and leaking joints around cladding and façade panels, on render & cladding joints, brickwork movement joints and façade panels.

Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Limmo Peninsula, tell us how high the joints are and how to reach the back of the building.

Every job is covered by our 12-month guarantee, wherever you are in Greater London.

Signs you need external mastic in Limmo Peninsula

Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.

If you can see any of these, it’s time to have the joints looked at:

  • Brick movement joints where the sealant has split
  • Joints pointed up with cement by mistake
  • Failed sealant between panels on a façade
  • Joints where the bead has come unstuck

As a London address, Limmo Peninsula can be tricky for parking: let us know about parking bays, permits or a driveway.

  • The length of the guarantee
  • Is the old sealant removed completely?
  • How the surfaces are prepared before sealing
  • How hidden problems are handled

Limmo Peninsula questions

Do you cover Limmo Peninsula for external mastic?

Yes, Limmo Peninsula is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.

Do you work for landlords with property near Custom House station?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.

Will you leave a mess?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Do you remove the old sealant?

Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Can you work on commercial sites?

Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Is it OK to seal over old sealant?

No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Walls and rooflines in Limmo Peninsula

London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. Historic houses like Queen's House (about 2.1 miles south) are a reminder that the area around Limmo Peninsula has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Homes close to Church of St Luke include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Custom House station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Surface by surface

Copings and trims

Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.

Cladding and façade panels

Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.

Why act early in Limmo Peninsula

Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Limmo Peninsula, the repair is bigger than the sealant job would have been.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Why book with us

  • We leave the area clean and tidy
  • Fully insured
  • Approved under the ARBOMaster scheme
  • A choice of colours where the product allows

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Ask before painting over external sealant
  • Fix overflowing gutters above sealed joints
  • Act on the first splits you see
  • Look over the joints every year, ideally after winter

Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.

Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

How the visit works

All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. In Limmo Peninsula, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We look at every joint and agree a colour to suit the wall.
  2. We take out the old sealant until the faces are sound.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about parking restrictions
