Grade II Listed Refurbishment – Lymington

The Problem

Waterstones Lymington store was in need of a major refurbishment. The decorations were tired with paint flaking to both the masonry and the woodwork. The windows were seriously decayed, the flat roofs were letting in water, the lead work to the main flat roof valley had been stripped out and the lime and plaster ceilings needed re-instating. Asbestos cement sheet and insulation board also required removal.

With the building being Grade II listed, strict guidelines from Conservation had to be followed.

FPM’s Solution

A complete overhaul was required so the works were broken down into their individual elements which included: stripping all felt roofs and re-covering with a three layer system including a new decking set to the correct falls; forming the main flat roof valley with new boards and making water tight with the introduction of new lead throughout. The lead had to be stepped in order to meet the Lead Association’s guidelines.

Sash windows that had rotted were replaced; these were manufactured to the same specification as the originals. Ceilings that had either failed or were installed in plasterboard were reinstated with lime plaster and horse hair. All modern paint coverings to the masonry front elevation were removed and Conservation friendly coatings, as supplied by Keim, were re-introduced.

The Full Story

FPM tendered for the works and once awarded the contract, met with the local conservation officer prior to works commencing to discuss the requirements of both parties. A working plan was established and a specification agreed.

The first priority was to make the building water tight, therefore all the existing felt coverings were stripped and all decking was renewed. The correct falls were created then re-covered in a three layer system. One of the early challenges was to prevent further water ingress and to keep the floors below dry. At times ceilings were exposed, as the old felt and decking was stripped, so time was of the essence. Whilst stripping the felt, an original lead valley was discovered to have been stripped out and formed in felt. The valley boards were rotten and there were no longer any steps within the valley, the decision was made to strip this out completely.

The valley was formed between two pitch roofs and into the roof void where it ran through the void exiting on the other side of the building. The new felt was laid and the lead work began. The final product was a fully lined and stepped lead valley.

With the roof now water tight the damaged ceilings could be removed and reinstated to their original state, that of lime plaster and horse hair.

Some of the old sash windows were removed and taken away to the joinery shop where replicas were manufactured then reinstated. In the meantime the remaining sash windows were completely overhauled which required the scarfing in of new timber and left in a good working order with new cords and weights re-introduced.

Decorations followed. The lime wash of the original front elevation had been over painted with modern paint coverings which were peeling away. In places the render was exposed. Guided by the Conservation Officer, FPM had samples of the render taken and tested. The result of the test was that the render was indeed a lime mortar. All coverings were stripped back and, where required, patch rendered with a lime mortar mix. The covering applied to the render was a Keim mineral paint which was breathable. The windows were painted in a modern paint (in accordance with guidelines).

The findings of the original refurbishment and demolition survey highlighted that there was asbestos content on site that required removal. FPM contracted the services of an asbestos removal company who removed all undesirable materials under stringent control measures.

All of the works were carried out with health and safety as a priority, whilst adhering to Conservation guidelines.

The finished project is a fine example of a Grade II listed building restored to its former glory.
