Painting a space in your home is not always very difficult; many homeowners can tackle adding a new coat of paint to the bedroom without much hassle. However, this doesn't mean that all painting jobs are manageable for homeowners, and some are downright unsafe. Note when it can be good to leave a painting job to a commercial painter rather than trying to address the work on your own.
If you suspect your home might have lead paint
Lead paint has been outlawed in many areas of the world, but this doesn't mean that the paint was automatically removed from homes once it became against the law to use it. Scraping away at any lead-based product and paint in particular can mean creating dust and other fragments that you might inhale even with a dust mask, and which you might track back into your home through your clothes and shoes. A commercial painter will know how to remove lead paint safely and without harm to you or your home.
Painting over rusted metal pieces such as stair railings and banisters or fences is not as easy as you might assume. Even if you sand down those rusted spots, they might be soft and weak; covering them with paint can then mean simply covering over a spot that needs more repair than sanding. A commercial painter can note if a metal pieces should be soldered or otherwise repaired before painted. They can also note if there is a cause for the rust that you should address before painting, so the new paint lasts as long as possible.
Don't assume that you can easily reach your home's exterior eaves or the cathedral ceiling inside with a standard ladder. Not only is it difficult to balance while painting on a ladder, the ladder itself needs to be set up a particular way so it doesn't collapse or fall backwards. An older ladder may also not be strong enough to hold your weight as well as the weight of a heavy paint bucket, and moving around on a top rung can cause added pressure that can cause the ladder to break. There is also the chance that an inexperienced painter might drop something and cause injury to someone below, or cause damage to your home. Rather than risk this type of accident and any resultant injury, it's best to leave painting at elevated heights to a professional who will have scaffolding pieces and take all necessary precautions for safety.
