General trades versus a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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.

How we handle facade sealing in Old Basing

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We plan for that and keep you updated. If you are dealing with perimeter sealant that has split or peeled away and new sealant peeling off old mastic, we can help. One point of contact handles commercial sealant work in Old Basing from the first photos to the final walk-round, whether it’s one building or several.

Conversions around smaller places like Old Basing often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. What matters most for a job in Old Basing is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  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

  • Move anything stored against the joints
  • Agree which areas must stay open
  • Share your working hours and any access restrictions

FAQs: Old Basing

Is Old Basing too small for you to travel to?

Not at all. Old Basing is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is Hatch Industrial Park, near Old Basing, within your area?

Yes. Estates, retail parks and business parks around Old Basing, Hatch Industrial Park among them, are all within reach. A few photos and the unit address let us price the work.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Do you replace failed glazing units?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Quoting for work in Old Basing

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Removal of failed or old sealant
  • The size and state of each joint
  • Any access equipment needed
  • How much there is to seal

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • The site address and postcode
  • Specification clauses that apply
  • What the building is and how it’s used
  • Anything awkward about access or site hours

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or send photos by email.

What we’re called out for in Old Basing

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

These are often picked up first by site or facilities staff:

  • Perimeter sealant that has split or peeled away
  • Cold air coming in at window perimeters
  • Damp patches beside frames after rain
  • Failed seals around shopfront and entrance frames

On a healthcare site such as Basingstoke and North Hampshire Hospital, 3 miles west of Old Basing, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What your quote should include

  • The named product and why it was chosen
  • How long is the guarantee, and what does it include?
  • Their public liability cover
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

After the work

For the best life from the joints:

  • Check the asbestos register before old mastic is disturbed
  • Avoid harsh cleaners on facade sealant
  • Don’t wait for a second leak before calling
  • Avoid patch repairs on failed facade joints

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.

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.

Old Basing is about 44 miles from central London.

When a school such as Old Basing Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.

Different surfaces, different methods

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.
