There’s no need to feel ashamed if you’ve got a worse-for-wear bathroom that’s suffering from mold growth. You’re definitely not alone! Cleaning up mold in a  bathroom remodel and making it more sanitary is easier than you think. Most of the basic mold-busting techniques you’ll find below are well within the reach of an experienced DIYer. For the very best results, of course, you can always turn the job over to a professional handyman!

Grout And Sealant

In most neglected bathrooms, the sealant and grout are among the first items to suffer. Restoring them to a like-new condition goes a long way towards improving your bathroom’s appearance. In the case of solid ceramic grout, intense steam cleaning can work wonders to eliminate dingy discolorations and brighten up the tile work.

Sealant is usually too badly degraded to salvage in a moldy bathroom. You’ll need to replace it. Use a high-quality silicon-based sealant that resists moisture and forms a flexible bond. Many manufacturers offer sealants specifically formulated for bathroom use that are impregnated with anti-bacterial compounds. Using these is highly recommended.

Dealing With Moldy Paint

You may well have unappealing mold growing directly on your bathroom’s finish surfaces. This is especially common on painted surfaces (like ceilings) that are exposed to intense moisture and heat. The best way to deal with surface mold like this is to steam-clean the surface and then apply a natural sugar soak. Follow this up with a commercial mold-killing product applied to the entire surface.

This intense treatment will usually damage the surface of the paint. To restore the pristine appearance of your walls and ceiling, use ordinary scraping and sanding techniques to remove loose paint. A heat gun comes in very handy here, as you want to make sure the surface is as dry as possible before repainting it. Select a paint that’s been formulated with mold-resistant ingredients; these products can kill existing mold as well as prevent new growth from occurring.


One of the biggest factors promoting the growth of mold in the bathroom is a lack of proper ventilation. If your bathroom doesn’t have an external vent, you should strongly consider installing one. This can be a rather expensive proposition, but it makes an enormous difference in the fight against mold. Using a vent to extract humid air after you use the shower or bath makes it much more difficult to mold to start growing.

Eliminating Hard-To-Clean Areas

In many bathroom layouts, stock fixtures are installed with little regard for the way their dimensions fit into the existing room. This can lead to tight, open gaps that are difficult to clean. These spaces end up being havens for all sorts of debris and moisture, and they’re ideal growth environments for mold.

If you have the time, resources, and talent, you should strongly consider sealing off such gaps using water-resistant sheetrock and anti-bacterial sealant. The new surfaces you create can be tiled or painted using the same kind of mold-resistant paint mentioned above.

While every bathroom renovation job has its own idiosyncrasies, the steps discussed here are broadly applicable to most bathrooms with mold issues. If you need additional guidance cleaning up your own moldy bathroom, feel free to consult with a professional handyman or contractor.

Elbert quoted best price, helped design and then delivered timely on an unconventional project to improve disability... access throughout our home. Replacing a treacherous step-down into a family room with a custom landing, ramp and rail, he reversed the swing of an existing, large interior French Door and created a new "Hobbit Door" doubling access for all our family members to make quicker, safer exit from the house in case of emergency and more easily enjoy the garden. A new Barn Door conceals it beautifully!read more

Preferred Contractors built us a 26 by 10 composite deck with a awning that covers half of the deck. The covering is... connected to the roof by sky lifts and the whole project looks awesome. Elbert and Lane were able to answer questions and provide explanations and adapt to requested changes. The price was very good and the quality of work was great. Thanks for the deck outstanding deck and covering guys!read more

Elbert installed a new door for us which looks great and created a railway stair guard which he had never done before... now. His work was outstanding. He is easy to reach, personable, knowledgable and fair in his pricing. We will need more work done on the house at some point and we will without doubt go to Elbert more

We had Elbert replace some dry-rotted supports on our front porch as well as our carport. He arrived on schedule for a... free estimate and we thought he quoted us a fair price for the work. He arrived on schedule to do the work, did a great job and cleanup when he was finished. We are very happy with his work and would use him again for any other projects as well as recommend his work to more
