How we handle facade sealing in Lydd-on-Sea

Managing agents and owners in Lydd-on-Sea ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have old perimeter mastic that has dried out and weathered joints at frame-to-structure perimeters, we can put it right. Looking for mastic applicators who cover Lydd-on-Sea? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Around smaller places like Lydd-on-Sea, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

When to call us in Lydd-on-Sea

Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.

Look out for the following:

  • Sealant pulling away from frames or panels
  • Unsightly perimeter sealant on a visible elevation
  • Failed seals around shopfront and entrance frames
  • Water coming in around window frames

New units and refits on sites such as Peak Industrial Park (to the west of Lydd-on-Sea) need their panel and perimeter joints sealed to the specification.

What your quote should include

  • How the joint faces will be prepared and primed
  • Are they CHAS accredited or on Constructionline?
  • The terms of the workmanship guarantee
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Facades, frames and programmes in Lydd-on-Sea

Lydd-on-Sea sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Lydd-on-Sea included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

School extensions, at buildings such as Greatstone Primary School, typically run to the summer holidays, mastic included.

Lydd-on-Sea is about 10 miles south-west of Hythe, in Kent. Our applicators travel to Lydd-on-Sea for work on facade joints. Lydd-on-Sea is one of 931 places we cover in Kent for facade joints. There’s a separate page for Brighton, about 48 miles away.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Work on the window or framing system itself
  • Specialist high-level access methods
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.

Surfaces we seal

  • Shopfront frames
  • Coping and flashing joints
  • Cladding panel joints
  • Stone and brick facade joints
  • Window and door perimeters
  • Perimeter joints where frames meet the structure

Common questions from Lydd-on-Sea clients

Is Lydd-on-Sea 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. Good photos up front let us bring everything on the first visit.

Can being near the sea in Lydd-on-Sea affect the sealant we need?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

Will you check whether the sealant is causing the leak?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Lydd-on-Sea can be grouped with others nearby. You will have a fixed quote before work starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints
  • Tell us your opening times and when work is allowed

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Insist on a full cut-out when joints are renewed
  • Share access with other external trades
  • Check that rainwater leaves the facade the way it was designed to
  • Ask about asbestos in pre-2000 mastic

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
