There are occasions where we do charge for surveys, although we do often carry out surveys without charge.  There are a number of factors taken into account, such as; size and type of property, type of survey needed, whether you are a repeat customer or have come to us as a direct recommendation etc.  Generally, where an initial charge is made, this is refunded to you if you proceed with the remedial work specified.  There is no hard and fast rule on this and it is always best to call us to discuss your requirements.

We cover London and the South East, but please contact us to see if we can accommodate your request.

Yes! Preservation Treatments undertake the specialist work specified.  We do not generally carry out decorating, electrical and plumbing work which may be associated with remedial treatments.

Most of the work we carry out is done during normal working hours.  Our Surveyors will try to accommodate early morning appointments i.e. 8.00 a.m., as long as we have adequate advance notice.

Where we are carrying out typical damp, timber and waterproofing inspections, we would suggest leaving up to an hour for our Surveyor’s visit.  Naturally, this will be dependent on the type and size of the property, along with the extent of the inspection required.

We aim to provide our report/quotation within 48 hours following our inspection

We do not normally sell the products we use.  Once a product has been sold, we no longer have any control over the usage of the product.  Also, most of our products are sold for the professional user who undertake extensive health and safety, COSHH (Control of Substances Hazardous to Health) and product training.









This is always so difficult to say, as our work-load changes depending on the type of jobs at any one time. As a general rule, our lead-in times are between 2-6 weeks, which will be dependent upon the nature of the works we are undertaking. To avoid disappointment please call us as soon as you decide you want us to carry out the work at your property so that we can discuss and book you in for your preferred dates.

Specialist Rendering / Waterproof Rendering Works

This will entail the laying of polythene and hardboard sheeting or similar where necessary to protect the floor/walkways during our works. This is particularly important during removal/hacking off where plaster can cause damage to floorboards and wooden flooring in particular. This work is then followed by the wet trade of plastering.

Where possible we will also screen off the area with polythene, which will be taped to the ceiling. This is to limit the spread of dust throughout the property, as far as this is possible.

This is dependent on the type of work that you are going to have carried out.

Timber Treatments

Where floors are being treated, all furniture and floor coverings including hardboard, floor tiles, etc MUST be lifted and removed from the treatment area. This is to enable lifting of the floorboards at regular intervals across the full width of the floor to enable treatment to the underside of the floorboards, together with the joists/wall plates.

Specialist Rendering/Waterproof Rendering

All carpets must be removed where specialist rendering/waterproof rendering works are to be carried out prior to the arrival of our staff. Furniture and personal items should also be moved away from the treatment area, to enable our Technicians full access to the walls. If there are radiators fitted these will need to be removed for the duration of the works and reinstated following the works. All the electrical faceplates from sockets and light switches will need to be removed isolated and made safe prior to our arrival. It may also be necessary to remove / un-clip cabling for alarms, computers etc. to avoid such cables being damaged. Please discuss any of the above with the Contracts Office.

Whether you can live in your property during our works depends on the extent of the work and where in the property it is being carried out. We aim to keep disruption to a minimum but due to the nature of our works there is likely to be dust especially if we are carrying out damp proofing/specialist plastering works.

If any member of the household is asthmatic, pregnant, small children, and pets, or has a health condition which could be made worse by disruption and dust, they should vacate during our works. If timber treatment has taken place in a bedroom, although re-entry time is just one hour, we advise that you do not sleep in this room for at least one night, following treatment.

Manufacturers of the timber insecticides/fungicides (which are water based) state that they should be touch dry in one hour, depending on timber and ambient conditions. However, this can vary during the time of year treatments are carried out and weather conditions prevailing. Always contact our office for further information/advice.

For all types of treatments, we need access to electricity and water. We also require access to welfare facilities (W.C. and hand washing) for our technicians for the duration of our works. If we carrying out rendering / re-plastering works, we would also need a designated place to store and mix materials.

When we remove the rubbish, it is bagged up and usually driven back to our fully licensed skip for removal. When we have a large quantity of debris this will be bagged up and we will dispose of it using a third party, skip or lift and load service. We always ensure that every waste removal service we use has a valid waste removal license.

It is always advisable to let your neighbours know if you are going to have noisy work taking place but when work is going to take place on a party wall (a wall that you share with your neighbour), which intrudes into that wall, this is a legal obligation under the Party Wall Act of 1996.

We aim to arrive between 8.00 and 8.30 in the morning, subject to unforeseen circumstances i.e. traffic. Leaving site in the afternoon will be dependent on the nature of the works this can be anytime from 3.00 – 4.30 p.m depending upon the type of work and stages of that work.

Most of our customers let our Technicians in and go to work; some leave a key with a neighbour or managing agent so they don’t have to take any time off work at all.

When we have finished it is important to let any plasterwork dry out naturally, do not force dry as this can cause cracking. It is best to discuss with the Contracts Department when skirting boards can be refitted, radiators and electrical sockets and light switch if applicable.

We do appreciate Customer Feedback and a small tick-box form will be sent along with your invoice.

New plasterwork may be redecorated after 4-6 weeks, using micro porous, water-based matt emulsion, providing the walls appear visually dry. It is essential that the walls are not coated in any impervious material, e.g. vinyl silk, eggshell or gloss, wallpaper, etc.

Where rendering has been carried out, items cannot be fixed to the treated area until the plaster is dry.

Where possible fixings through walls where Structural Waterproofing works have been carried out should be avoided. Some specialist fixings can be used, but please contact our office, to discuss in detail, as this will be dependent on the type of works carried out.

As soon as you have paid your final bill we will send your Certificate of Guarantee out to you, along with the receipted invoice(s).

If you have any further questions please do not hesitate to contact us and a member of our team will assist.
