“Bathrooms & Toilets”


Under Stairs Toilet €1,000 €3,500

Installing a toilet under the stairs is a great way of using space and can be a useful solution for a growing family or for older homeowners. The area should already be fairly self-contained, so there is not a lot of construction work to do. However, there will still be a fair amount of work to do in terms of plumbing, electrics and ventilation. All of these will need to be up to scratch to comply with building regulations, so it is worth the cost to get an experienced professional in to undertake to job and to coordinate any additional tradesmen that may be needed.


New Bathroom €2,000 €6,000

Whether you are turning a spare bedroom into a bathroom, creating a new bathroom or putting one in an extension, you will need to hire an experienced professional to undertake the job. This is a job that will require some construction work, as well as plumbing and electrical work, so your money will be well-spent on an expert who has built or installed bathrooms in a number of homes before.

The creation of a new bathroom is not a complicated process, but it has to be undertaken in the right order and to certain standards for it to comply with building regulations and match your dreams of a new, practical space in your home.


Build & Install En-suite bathroom 2m x 2m €3,000 €6,000

Ensuite bathrooms have become increasingly popular in our houses, creating a haven for parents next to the master bedroom or giving added privacy to an elderly relative, children or visitors to your home. If you think you may want one installing then it is best to get a builder in to see if you have enough space to carve out of your bedroom, walk-in wardrobe or spare room, as well as if the ensuite will comply with current building regulations.


“Ceilings (based on 4m x 3m area)”


Remove Stud Wall €450 €700

If you are removing a stud wall from your home to open up the space or change the layout, then you will be left with work to do at both floor and ceiling level to make good. Before any work is done to remove the stud wall your builder will first have to check that the wall is not load bearing in any way. They will also have to check that there are not heavy items sitting above it, such as water tanks. They will also have to check the walls for electricity and other services.


“Doors & Windows”


Block up an Existing Doorway €200 €500

You may find that you need to block up an existing doorway as you want to change the layout of your home. You may also have an additional doorway that you don’t need after knocking your dining and living room into one. This is a straightforward task for a builder or internal renovations specialist and should be able to be completed in a couple of hours.


Create Doorway in Stud Wall & Hang Door €350 €600

Creating a doorway in a stud wall should be a simple job for any experienced builder or internal renovations expert. These walls are not load-bearing, so they will not usually need to be strengthened once the doorway is made. They will also need to check if any services run through the wall that is being partly demolished. If this is the case you may first need to ask another professional to reroute services such as electrics or plumbing.


Create Doorway in a Brick Wall & Hang Door €450 €1000

When it comes to creating a door in a brick wall the main thing you should ask yourself is whether the wall is load-bearing or not. If you are not sure then your builder should be able to advise you. If the wall is load-bearing then the job will be more complex and time-consuming, as the builder will need to shift the load to the remaining parts of the wall. The joists and/or the wall may need to be supported as the work is done and a supporting lintel or beam will be placed above the door to support the wall.


Replace Doorway With French Windows €300 €2,500

Taking down your current door and replacing the doorway with French windows is a job that can vary greatly, depending on whether you want to make the doorway larger to encompass the French windows. If this is the case then some demolition work will be required and the doorway or walls may need to be strengthened.

If you just want to use the same doorway then the job is a fairly simple one. You will need a new or adjusted doorframe and your builder will then fit the French windows to this frame. If you are replacing a window with French windows then your internal renovations expert will need to take out the current window and demolish a part of the wall below the old frame. They will also need to remove window frames and sills before proceeding.




Install a New Kitchen €2,500 €7,000

Installing a new kitchen in your home is one of the largest internal renovation jobs that most people undertake. The results can be stunning, transform your home and add value to your property, but there is a lot of work to get to the final product. The style and materials of your kitchen will make up a good deal of your budget and this is probably something you will choose or at least have in mind before you hire your builder or kitchen installer.

Whether you are buying a ready-made kitchen or you wish to have one custom-made, your builder should be able to advise you on what and where to buy. Do ask to see photographs of past work, as any competent tradesman will be happy to send them to you or even show you testimonials or examples of work in your area. The builders will start off by measuring your kitchen as well as looking at whether you will require further electrical outlets, lighting or extra plumbing work.

The job is as large as you want to make it and it does help to hire someone who is good at planning and who you feel comfortable working with. Their expertise will be invaluable as the job progresses and you will find that you are paying for experience as well as just labour. A good kitchen fitter will be able to advise you on everything from the kind of finish you would like for your cabinet doors to which kind of cooker hood to choose.


“Plastering (based on 4m x 4m area)”


New Plaster on Walls & ceiling €500 €800

The cost of having new plaster on your walls or ceiling will largely depend upon the size of the room or walls that you wish to have plastered. Renovation of the plaster will first mean the removal of the current plaster, which can be a messy job. You should make sure that you remove all the furniture you can or cover items with dust sheets. You may also have to budget for a skip so that the builders can dispose of the plaster waste from your current wall.

Do always ask your builder if this included in their quote or will be extra. In most cases your plasterer will be putting the new plaster on to existing plaster board. If the old plaster board is damaged or damp then your plasterer will suggest first installing new plaster board before starting the work.

They may also suggest this will be easier and cheaper in certain cases. New plaster board will already have been fitted if the wall is a new wall. With internal brick walls, plaster will have to be chipped off before new plaster can be applied.


Skin Walls & Ceiling €250 €700

If the plaster on your walls and ceilings is generally sound but you have extensive cracks or you are unhappy with the finish, then you may choose to have it skimmed rather than removed and renewed. This is generally a cheaper option, as your builder will not have to remove the old plaster before starting the job.

An experienced builder or plasterer should be able to advise you on the best course of action, whether you want to cover up an artex ceiling or simply freshen up your plaster and the finish in your home. A plasterer will first cover up and fill any cracks or areas that need repairing before skimming the wall or ceiling with plaster. You should end up with a smooth finish that can then be painted or papered. The job is usually straightforward, although covering textured surfaces and finishes on your walls and ceiling will take longer and therefore be more costly.


“Walls (based on 4m x 3m area)”


Remove a Stud Wall & Make Good €250 €700

If you decide that you want to change or improve the layout of your home then removing stud walls is a good, cheap way of going about it. This could be to make a room more open plan or knock two rooms into one larger space. The first thing your builder will need to do is to make an assessment of the wall and prepare for the removal of any electrical sockets, pipework or equipment that runs through the wall. They may need an electrician or plumber to carry out this part of the job or may have one in the firm that you use. Always ask about this as it could add to the cost of your job.

They will also make checks to ensure that the wall is not load-bearing and that things like ceiling joists are not connected to the stud wall. Demolition is a fairly simple task where the walls are not load-bearing (which is usually the case with stud walls) and are easy to dismantle without heavy work. The main difficulty is making sure that the wall comes down cleanly and does not cause any damage to other walls or décor.


Build a Stud Wall €500 €900

Building a stud wall is a simple way to divide up the space in your home and also to divide off rooms for new functions, such as en-suite bathrooms or utility rooms. A stud wall is a timber frame that has plasterboard nailed or screwed over the top to create a wall. Putting one up is simple for an experienced builder, but it is very much a skill that has to be learned.

Stud walls are hollow, so they make a great place to hide wires and services. Your builder will first have to come in and measure up and they will then go off to buy or collect materials for the job. This may be on the same day or at a later date. You may need to call in an electrician to put wires through the wall if your builder does not have one on their staff. You will also need to decorate the wall to fit in with your décor or call in a painter and decorator to re-do the whole room or match the new wall to your current scheme.

An experienced builder will know how best to build a stud wall to make it both strong and soundproof. Switches and sockets are usually offset so that outlets on both sides of the wall do not line up and so sound does not travel through the walls that way.


Remove a Brick wall (no RSJ required) €500 €1000

Removing a brick wall in your home is definitely a job for the experts. It is messy, dangerous and could well impact upon the safety and structure of your house. It is the kind of job where an experienced builder is required and is worth every penny. The size of the wall will largely dictate how long the job takes, but you are also paying for some pre-demolition assessment of the work by your builder.

They will first have to make sure that the brick wall that they are removing is not load-bearing and that the ceiling or other walls do not require reinforcement before the demolition starts. They may look at your house plans if you have them, or simply give the house a good inspection. They may also ask you about the listing status of the building, as listed buildings may require consent for any demolition work of this kind.


Remove a Brick wall & Insert RSJ €1000 €1,800

If you wish to demolish a load-bearing brick wall in your home then you will need a very experienced builder to do the job. Load-bearing walls are the ones that support other parts of the house, such as the roof or ceiling, so you will want to make sure that you get the job done right. Your builder will need to measure for and purchase an RSJ (rolled steel joist, which is sometimes also known as an I-beam or H-beam), which will be fitted to shore up the walls and ceiling around the demolished wall.

The builder will also inspect the wall and the whole house to see where it is bearing load from. They may ask to look at plans if you have them, as well as looking in rooms directly above where any wall is being demolished. They will usually need a structural engineer to look at the wall. This part of the job is where the expertise of the builder and their team comes in and you can expect to pay for a good deal of inspection and preparation work. They will also be able to tell you whether the building work will need to be signed off afterwards by a local building inspector.
