For those with busy schedules, tackling home improvements can seem overwhelming. But upgrading your space doesn't have to be time-consuming or expensive. There are plenty of fast and affordable updates that can have a big impact on your home. These five projects will rejuvenate your space without the stress of an extensive remodel.

1. Erase wall markings.

Over time, scuff marks and grime can build up on your walls and make your space seem dingy. And if you've lived in your home for a while, there's a good chance your walls have seen better days. Spend a few hours scoping out marks, fingerprints and dirt on your walls, and attack them with a melamine sponge. Simply wet the sponge, squeeze out the excess water and rub spots away. This quick wall refresh will make your paint look cleaner than it has in years.

2. Tackle grout stains.

You fell in love with your tile floors because they're durable, water-resistant and cost-effective. But you've started to notice that the grout is dirty, stained or discolored. With a toothbrush and an afternoon spent scrubbing the grout, you can make it look as good as new. One cleaning agent popular for the task is a mixture of hydrogen peroxide and baking soda, but there are many options out there. If you want something fast, use a grout whitening pen to fill in discolored places as needed. The result should be crisp, restored grout lines.

3. Get an instant accent wall.

No time for a paint project? No problem! Use self-adhesive wallpaper for an ultra-fast accent wall that will instantly transform your space. These wallpapers come in all kinds of styles, including stick-on inspirational quotes, high-resolution photographs, and solid colors and patterns. If you're craving a change but don't want to mess with your walls, consider sticking wallpaper to the risers on your stairs for a multi-dimensional effect. No matter where it goes, self-adhesive wallpaper will add texture to your home and revive your space.

4. Fix little nicks.

If there's noticeable wear and tear on your wood finishes or furniture, there's no need to get them replaced. Just show them a little TLC. Use wood filler putty to fill in big nicks and cracks, then wait for it to dry. Next, sand the putty smooth and stain it to match the rest of the wood. Simple! For smaller scratches, use a stain marker to fill in the chipped areas. And for something even simpler, crack open a walnut and rub it on micro-abrasions to smooth them out. This speedy project will have your finishes gleaming.

5. Swap out hardware.

Outdated cabinet hardware can make your kitchen or bathroom look drab. Choose some replacement pulls, knobs and handles to give your space a quick, high-impact update. There are so many options for cabinet hardware, it should be easy to find a trendy style that matches your taste. Pro tip: If you're having a hard time deciding between a few different hardware styles, buy one of each and test them out before committing to an entire set. Once you choose the perfect hardware, simply unscrew your old knobs and change them out for a whole new look.
