Questions about Knights Enham

Is a smaller place like Knights Enham outside your area?

No. Places such as Knights Enham are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Could you schedule work at a campus like Andover College for the vacation?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work while the building is occupied?

In most cases, yes. We phase the work so most of the building stays in use.

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 handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do you use the sealant named in the specification?

The specified product is what goes in. If we think an alternative would suit better, we put it to you first.

Construction mastic in Knights Enham

Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, whatever the size of the scheme. If you are dealing with mastic snags holding up handover and frame gaps too wide for sealant alone, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Knights Enham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Knights Enham, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Our process

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Knights Enham, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. You receive a fixed quote listing scope, products and phasing.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Advice

When to call us in Knights Enham

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Choosing the right product for each joint reduces that.

Things that usually lead to an enquiry:

  • External joints sealed in damp or cold conditions that are now failing
  • Frame gaps too wide for sealant alone
  • A mastic package split between trades with no clear owner
  • Missed perimeter joints on a new elevation

Units on estates such as Glenmore Trade Park (0.8 miles south of Knights Enham) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

Why act early in Knights Enham

Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area normally clears more for less disruption, and avoids repeated visits. We can run snagging as its own phase before handover. Converted and older buildings near places like Knights Enham tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Why choose Mastic Doctor in Knights Enham

  • Joints cleaned back to sound surfaces
  • A Constructionline member, so easy to vet
  • Products installed to the manufacturer’s instructions
  • Matching to RAL references, product permitting

General trades versus a specialist

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.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Different surfaces, different methods

Fire-rated sealant where specified

Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control and we install what’s specified.

Snagging before handover

Snags normally come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.

Building and refurbishing in Knights Enham

There are several hotels within about 2 miles of Knights Enham. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

Projects at schools like Roman Way Primary School work to term dates, so mastic is programmed tightly. For a contractor working at a hospital such as Andover Hospital (Grounds), 1.3 miles south-west of Knights Enham, perimeter and facade sealing is planned around patients and deliveries.

Knights Enham is about 1 mile north of Andover, in Hampshire. Anywhere in SP10, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

After the work

Once the work is signed off, these steps help:

  • Get the mastic subcontractor involved early in the programme
  • Ask installers to correct oversized gaps first
  • Plan external elevations with the weather in mind
  • Brief following trades on areas that have been sealed

Record which products went where in the handover file. That helps the building owner maintain the joints later. Tell us what records you need and we’ll confirm with the quote.

Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels. Proper preparation, with the right silicone first time, keeps it off the defects list.
