Commercial clients in Aldingbourne

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.

Facade sealing for commercial buildings in Aldingbourne

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. Most enquiries involve previous reseals run over old sealant and leaks at window and door perimeters, across window and door perimeters, perimeter joints where frames meet the structure and cladding panel joints. A single leaking joint is often how a building in Aldingbourne first comes to us: we look at the rest while we are there and tell you what we find.

Construction in and around smaller places such as Aldingbourne is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Facade sealing in Aldingbourne: the local picture

The area within 2 miles of Aldingbourne holds a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Aldingbourne is about 52 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

Building work at universities like University of Chichester, 2.1 miles south-west of Aldingbourne, is often timed for the summer, mastic included. Historic houses such as Goodwood House (to the north-west of Aldingbourne) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Recladding or extending a unit at a site like The Woodhorn Business Centre, 0.9 miles to the south-west of Aldingbourne, brings panel joints and frame perimeters into the programme.

FAQs: Aldingbourne

Do you cover business parks and estates near Aldingbourne, such as The Woodhorn Business Centre?

Yes, sites like The Woodhorn Business Centre are within our area, along with the rest of Aldingbourne. Photos and a short description are enough for a first look.

Is Aldingbourne too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Should we check old sealant for asbestos?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

After the work

A few simple habits keep the new joints working:

  • Never let anyone seal over old sealant
  • Confirm the survey covers external sealants in older buildings
  • Report water ingress at frames as soon as it shows
  • Keep sills, gutters and drainage paths clear

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal across the elevation.

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 with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Aldingbourne can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Let building users know which areas are affected
  • Clear stock, furniture or equipment away from the joints
  • Explain the parking and delivery arrangements

Leave it or put it right?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. One visit to deal with every failing joint makes more sense than several trips to a place like Aldingbourne. Send photos of each area and we will quote for the lot.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why appoint us

  • Constructionline member for supplier checks
  • Matching to RAL references, product permitting
  • One number for every site we cover
  • Joints cleaned back to sound surfaces

Quoting for work in Aldingbourne

What shapes the price:

  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Distance, for remote addresses
  • Any access equipment needed

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

We can often quote from photographs and a few details. It helps to include:

  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them
  • Anything awkward about access or site hours
  • The product your specification calls for

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or send photos by email if you’d rather talk the job through.
