Knowing the Cost of Drywalling a House

This article will provide you helpful information about drywalling a house, including the cost, materials, labor and turnaround time of this home improvement project.

Drywalling a House Cost

When it comes to the drywalling costs, there are two things to consider and these are the material and labor costs. These costs can also vary on your preferences such as the quality of the materials you would prefer and the professional whom you would hire to install the drywall in your house.

Good quality panels cost around £4-5 and with this, a 12×12 ft room which is a standard room size would cost around £550. When it comes to the person who would install the drywall, it’s always best to go with a professional as they are the ones who already have an accreditation and would definitely give you a detailed quote.

To give you an idea, the following are the estimated costs if you will be hiring a professional plasterer to do the drywalling in your home with 3 different room sizes (with panels and drywalling) and duration of the job to be completed:




6x12ft room


1-2 days

12x12ft room


1-3 days

What is Drywalling?

There are actually two options you can choose from for your own home and these are drywall and plaster. Recently built homes have drywall instead of plaster. A drywall, also known as plasterboard, is a material that consists of gypsum inserted between two sheets of paper. Installing a drywall is much easier by just hanging and screwing it into the ceiling joists or through the studs of the walls which will create an even surface.

The joints and screw holes that are visible are sealed with tape and joint compound. If the joint compound has dried, a fine sandpaper is used to make sure that there are no lumps or obvious joins. This will then be perfect for finishing touches of your choice, whether paint or a wallpaper.

One of the reasons why it’s best to hire a tradesman and do the job for you is that these drywall sheets usually are 4 x 8-foot size and weight between 20kg and 35kg each and these should be carried and installed carefully.

Other Trades You May Need

After the installation and sanding down of the joins, the next thing that needs to be done is to paint or put a wallpaper whichever you prefer. Painting walls using paint rollers seems to be a very easy thing to do but it’s actually not especially if you want it done perfectly. With this, it’s again best to hire a professional painter.

These professionals are experts in what they do that’s why you can expect a wonderful outcome. Since you already invested in installing drywall in your home, you might as well get an experienced decorator for the finishing touches.

DIY? Or Not To DIY?

In doing this work for just small installations or touch-ups and your property is not listed, you no longer need planning permission. With these small works, all you need are a few tools and these are a bucket, mud pan, sanding block, drill, taping knife and utility knife. Aside from these tools, you also need other materials such as compounds used on drywalls, drywall screws, metal corner bead, setting-type compound, and fine sandpaper.

In addition, it would be helpful to get some advice from people who have done this and learn from the mistakes that they have encountered. The following are some tips you should take note:

  • Batches of your fillers should vary as you need to use thinner batches for hand taping while you need thicker for final coats.
  • To remove the bubbles of air, you can mix the filler using a potato masher
  • As you see gaps from top to bottom, fill all these with the setting compound
  • For each joint, you need to cut a “V groove” down and fill the “V” with a setting-type joint compound. After this, you cover the seam using the joint compound and tape. In doing this, you will be able to resolve the toughest issue in placing the two ends together.
  • To get rid of unwanted bubbles, you need to damp the drywall tape before you embed it in the joint compound.

Common Drywalling Installation Problems

Like any other house works, there are various issues that you may encounter in doing drywalling all by yourself and these issues can actually cause problems with your budget too. Some of the problems that you might encounter are the following:


In trying to make your work perfect, some of the DIY drywallers overdo sanding the compound which has dried and joints thinking that it will make the surface smoother. But if you do this the chance is higher in exposing the paper or fiberglass tape which is covering the seams or the worst is that it will affect the surface of the drywall. For you to prevent this from happening, you can put a light down on the floor to see any bumps that you need to even out.


You should be very careful in screwing the drywall in place as its surface can easily crack if you drive the screws too far. If the screws are driven too far, it will compromise the ability of the drywall to hold on to the screw.


Making sure that the panels are tightly joint might seem like a perfect thing to do but it’s actually not. If you place the dry panels too close to one another, there is a higher possibility for it to crack in the future because of what we call seasonal expansion. As much as possible there should be about 3mm space between each drywall panel.


This usually happens when you don’t have enough coats of mud. It’s best to have at least three coats of mud which are the tape coat, filler coat, and final coat. More often than not, DIY drywallers tend to forget and miss out on the final coat which is an important thing to do.

Drywalling without Plastering

Plastering is not necessary if you install a drywall as a lot of new homes nowadays are not even plastered internally. It is already common these days to just install plasterboard or drywalls. With this, there’s no need to have a plaster skim on the internal stud or the internal faces of the exterior walls.

One problem though if a drywall doesn’t have a skim coat of plaster or a sealer is that its surface can be very absorbent which makes it difficult to paint. Even though it is possible to apply paint or wallpaper directly on the drywall, it’s still not the ideal thing to do.

Although a skim coat of plaster is best, there’s actually a cheaper option for you to have the same output which is to use a sealer product to seal the drywall then you can apply the paint or wallpaper. It is best to prepare the drywall by painting on a special adhesive compound aside from applying a skim coat or veneer of plaster.

Negatives of Drywalling without Plastering

For property developers it is easier and cheaper to install a drywall without a protective coat of plaster but this is not the best option for homeowners especially when they want to paint and decorate their home. A drywall without a skim coat absorbs the paint while in using a wallpaper, you should really be careful when you will have it removed as it will damage the drywall.

There are those trying to remove and scrape off their wallpapers and without knowing that they are already scraping the surface of the drywall and no longer the wallpaper.

Installing Drywall over Old Walls

Old and damaged walls can still be restored and the quickest and cost-saving way to do this is install drywalls over them. With this, you will be able to cover old walls efficiently and less expensive as this doesn’t require too much work. On the other hand, drywalls alone are not as effective being a sound barrier but you can always add an insulation layer underneath it before the finishing touches.

Drywall vs Plaster

Wet plastering has been widely used for the longest time and this has been considered as a traditional process as this creates a sturdy finish which is perfect for painting and wallpapering which is also a common practice. Having different layers of hard-wearing materials such as lime, gypsum or cement, wet plaster creates a texture with levels of airtightness and sound resistance and these characteristics can’t be found in using drywalls or plasterboard panels.

On the other hand, the downside of plastering is that it requires extensive labor and specialized skill compared to drywalling. It is faster to install drywalls as these come in large sheets which are ready to install and fits directly on your walls. Although a skim coat or a sealant still needs to be used over a drywall, it is still easier to install compared to a wet plaster.

When it comes to material cost excluding the labor, the wet plaster is a lot cheaper compared to the drywall. In plastering, what really costs a lot is the labor from skilled persons which is required and this can’t only be done by anyone without expertise. In drywalling the labor and skills required are really not that much.

Moreover, wet plastering a wall in a traditional way would take a lot of days to be completed while drywalling is usually done in just hours.

Which is the best thermal insulator?

When it comes to thermal insulation, it has been known that there is no much difference between drywall and plaster as the composition of the wall is what’s important. Although it’s good to know that it is simpler to add more thermal insulation on a drywall than on a plaster.

Just another small advantage with plaster is that it can be efficiently sealed compared to a drywall which you still need to cut according to the shape of your wall which may not be perfectly done especially on skirting boards. With all this information, having an insulated drywall with an effective wet plaster skim coat finish would give you the best outcome for your walls.
