Stone & Plastic Repair

A blend of Lime, fine aggregate filler and additives forming various brands and specifications of conservation approved stone repair mortar designed for use on natural stone and period brickwork. It can be matched for colour and finish to almost any masonry.

Restoration and Repair Mortars

Specially formulated mortars based on Natural Hydraulic Lime and aggregates for the repair or simulation of masonry, brick or stone. Neutral white or pre coloured mortar supplied in 1KG to 25KG bags to which mixing water is added. Mixing and use: Can be mixed manually or mechanically by whisk, adding up to 180ml water per kilogram of Lithomex used. Mix well for 3-5 minutes. The application surface must be clean, free from dust and oils. On porous surfaces, ensure that suction is controlled by pre-wetting and apply Lithomex before this is fully dry. Never apply to surfaces that are over saturated or have standing water.

Shaping and forming of details can be carried out for up to 1 week after placing by scraping to profile or level with metal tools, such as the edge of a trowel or steel float however most shaping and finishing work can be done within 24 hours. Sculpting, using appropriate tools, requires waiting up to a week or more depending on the weather conditions. Its unique qualities allow it to be tooled, shaped and sculpted even after the final set has taken place. This affords sufficient time to achieve the very highest standard of work with the best quality reproduction.

Where ashlar masonry or very finely jointed masonry has had considerable damage to the arises, flush finishing in Lithomex with a false struck joint is the ideal solution. If building details are damaged and require repair prior to the facade being lime washed or painted, plain Lithomex should be used as it will readily accept lime washes and paints.

On rendered areas Lithomex can be used to form decorative stone or brick features such as mouldings and cornices.

I’ve known of Tom Ferris and his work for some time. I have used him for private work on my property – which this review covers – but as a Trustee of a Grade A heritage property in the Borders, I have recommended and used him for work on that elevated level of craftsmanship. I have also seen his work on at least three other Grade A properties. I regularly recommend him to Boards of Trustees and private individuals who own heritage properties. He worked for me on a private project, creating a curved wall as part of a new remodelling of an area of my property. He produced a result that is frequently praised by those who see it for the first time.

I have experience of T J Ferris Stonemasonry’s work both in repair and new stone build. The quality of their workmanship is excellent. They have built a new stone wall for me personally and we are very pleased with it. They have also repaired our Georgian garden wall. TJ Ferris Stonemasonry have undertaken repair work, at a competitive cost, on the Category A listed ancient monument of Coldingham Priory – treating 13th century stonework to reduce porosity and repairing Victorian weathered sandstone.

Tom and his team recently finished a number of stone and building repairs at my house and I cannot recommend them enough. The job was complex yet Tom and his team provided me with a comprehensive estimate and plan which was followed through keeping us in budget. The craftsmanship was first class and Tom’s team were professional, courteous and tidy throughout. I am delighted with the results.

Thomas and his team removed cement mortar from a couple of elevations on a cottage. They then repointed using lime mortar. A brilliant job with minimal disruption. We have dry houses now! I would happily use Thomas Ferris again.

Thomas completely replaced the platform at the top of my Colony steps, repaired some of the steps, repaired the walls on either side and repointed the walls along the pavement. Everything was colour matched to fit with the original steps and I’m delighted with the final result.
Thomas and his workers were really great, friendly and polite and worked so hard to do everything just right. Thomas kept me informed every step of the way, was very thorough when finishing off and made sure everything was tidied up. A very positive experience!
