Extension FAQs

Yes, the same answer applies as with loft conversions; we have over 50 years of experience in the building industry and the expertise to provide a complete service from the initial free consultation and survey through to completion for both extension and loft conversion projects. The service covers all the administration including the production of our specialised computer automated design drawings tailored to each customer’s specific requirements. The service also includes; structural calculations, applications for building regulations and a lawful development certificate or a planning application if required. We also take care of payment of all associated fees that become payable the local authority.

No, we do not require a deposit. The only financial commitment a customer has to make at the point of signing a contract is to agree to pay for the administration. This includes the cost of the drawings and structural calculations and the fees payable to the local authority to obtain the necessary permissions for the project to go ahead.

No, the only subcontractors we use on regular basis are, a registered scaffolding company, a registered Electrical contractor and a registered heating engineer all of which we have used successfully for many years and produce certification as required forming compliance with building regulations. The only other sub-contractor we use is a registered ground works and bricklaying specialist company that have their own diggers and are totally reliable. Work is continuous once a project is underway through to completion and we are totally in control of everything including our directly employed staff that carries out the majority of the work.

Yes C & A Johnson Ltd can offer a ‘Masterbond Warranty’ that is insurance backed and promoted by the ‘Federation of Master Builders’ of which we have been members for many years. Our history is testament to the fact that if there are any teething problems we always return to site to sort them out. Customer care does not stop when the project is complete.

In any event all the work will have the back up of drawings and structural engineering calculations that will have been passed by building control. Subsequently the work will have been inspected throughout with certificates in place covering any electrical or gas installation and a final certificate from building control showing full compliance with all the regulation has been achieved.

Not always. It is often possible to carry out a single storey extension to the rear or the side elevation of a property or, a porch to the front without the need for planning permission.

Rules have been relaxed in recent years and a lot of single storey extensions we have carried out have not required planning permission. However, all two storey extensions do require planning permission.

These are issues that are usually able to be discussed and resolved during our initial free survey and consultation when measurements are taken to produce a provisional design drawing on which we can base a specification and cost.

Yes. The party wall act was introduced in 1996 and serves a useful purpose. Although it is a civil matter and has nothing to do with planning or building regulations we are able to help our customers to reach an agreement with any immediate adjoining neighbours and have documents available to assist in this process if a party wall act agreement is required.

No, usually not but there will be some disruption and some dust is inevitable. Our company takes great care to ensure the work is programmed to ensure the most invasive work (breaking through and installing beams) is carried out as late in the project as practicably possible when the dirtiest work involving in the actual building process is almost complete. All reasonable measures are put in place to minimise the spread of dirt and dust within the occupied living area throughout the entire project and specifically at the point of breaking through. Dust sheets and tape and polythene are used within the areas affected by the most invasive work. We carry our own vacuum cleaners and make every effort to leave the property as clean as possible at the end of each working day but do request the client removes personal effects from the affected areas prior to work commencing at the point of breaking through.

No, there is always a saving to be made in cost per square metre of the floor area gained with a two storey extension as the building is on the same foundations and has roughly the same size roof over it as a single storey extension but is a little more complex in its design.

Yes, we can supply kitchen units and offer a kitchen installation service at competitive prices providing 3D kitchen design plans and literature on request. We can also offer a bespoke kitchen design service providing made to measure units and facings with Corian or Granite work surfaces to complete the project and our customers are able to visit the factory to see samples of the units and an assembled kitchen.

Yes, we have fitted many Bi-fold doors to kitchen/dining room extensions and have designed extensions specifically suited for dual purpose family living space with maximum natural light.

Bi-fold door extensions are popular as ‘Garden rooms’ extending dining rooms and lounge areas. This type of extension adds significantly more value than a conservatory as they are thermally efficient and are accepted as proper buildings by building societies in the true sense of the word being certified in full compliance with current building regulations.

Yes, we can offer competitive prices for heating installations and boiler changes as we are continuously working with our registered ‘Gas safe’ heating engineer who has many years of experience. He can offer professional advice to our customers on types of boilers and systems that are available and we work with him to ensure the timing and continuity of the project is managed to ensure pipes and flue systems are installed at the correct time.

Yes, as soon as a customer has selected tiles for any walls or floors and the exact areas to be tiled have been determined, we can provide a tiling service. We do offer our customers the opportunity to use one of our accounts at a major tile supplier to purchase tiles at a discounted rate.

Yes, we are able to provide a decorating service if required.

Yes, if we have a potential customer who is seriously considering using our company as their favoured contractor we can put them in touch with a previous customer. They are able to view a completed home extension, discuss our performance and the service we offered and are then able to make an informed decision prior to commitment.
