Need facade sealing in Old Town?

Why act early in Old Town

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Facade sealing in Old Town, done properly

Managing agents and owners in Old Town 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. Each job carries our 12-month guarantee. We work on window and door perimeters, stone and brick facade joints and coping and flashing joints, and the failures we are asked to look at most are perimeter joints where frames meet the structure and cold air coming in at window perimeters. A single leaking joint is often how a building in Old Town first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Conversions around smaller places like Old Town often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Backing rod, priming and other preparation
  • The product specified
  • Site requirements such as inductions and permits
  • Location, for remote and island sites

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Clear photos of the problem areas
  • Access details, including height
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, call 01277 525 020 or email drawings and photos.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Share access with other external trades
  • Confirm the survey covers external sealants in older buildings
  • Keep the sealant details on the building file
  • Avoid patch repairs on failed facade joints

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in Old Town is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Agree which areas must stay open
  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints

Related advice

Should maintenance staff do it?

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

FAQs: Old Town

Can work at a site such as University of Brighton Eastbourne Campus fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Our building in Old Town is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. When you call the office on 01277 525 020 or email a schedule or drawings, describe the access, and we’ll agree the approach together.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send photos by email. Include photos or drawings if you have them.

Surface by surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

Window and door perimeters

Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus, neutral-cure product suits most frame-to-wall joints.

Facades, frames and programmes in Old Town

With the shore within about 2 miles, Old Town counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

Units on estates such as Courtlands Road Industrial Estate, 1.1 miles east of Old Town, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a campus such as University of Brighton Eastbourne Campus, 1.2 miles to the south of Old Town, new teaching buildings and residences are usually built and refurbished around the academic year. Projects at colleges like East Sussex College Eastbourne (1.1 miles north of Old Town) tend to run to term dates, so the mastic is planned tightly.
