6 Mobile Home Maintenance Tips

6 Mobile Home Maintenance


Just like a site-built home, a mobile home needs routine maintenance and inspections to keep it in top shape. The following mobile home maintenance tips can help you keep your home healthy and beautiful.

Mobile homes are pre-fabricated structures that were built in a factory before July, 1978. We love factory built homes because they are less expensive than a home built on-site but are equally attractive and comfortable. Manufactured homes can be any size, from small, single section units to large multi-section units. They can have whatever features a site-built home can have; fireplaces, cathedral ceilings, and even basements. You can even have a 2 story manufactured home!

1. Make Sure Your Mobile Home is Level

The most important tip a professional can give a mobile home owner is to check your home every year to ensure the it is level. Mobile homes can settle over time. If a mobile home is not properly leveled it can cause several issues: doors and windows won’t shut properly, cracks appear in walls, and leaks occur. You can buy a water level online for less than $60.

2. Skirting Ventilation

A mobile home’s skirting, or perimeter enclosure as the pros call it, is more important than most realize. Skirting acts as an insulator for the whole home, it adds protection from pests, and it adds curb appeal. Skirting should be secure so animals can’t get in but have adequate venting so humidity can’t damage the home and mold can’t grow.

Proper ventilation is serious business. There is a formula (1:150) that you can use to ensure you are giving your home the proper skirting ventilation based on your square footage. In other words, there should be one square foot of venting for every 150 square foot of space under your home. You will need to install these vents within 3′ of each corner (to prevent dead air pockets).

Please note: your home’s manual should provide guidance (or possibly a different formula). Skirting manufacturers will also give you guidance on proper ventilation protocol.

3. Roof Maintenance

If you have a mobile home with a flat roof you will need to reseal or recoat it regularly. Some manuals state this should be done every year.

Make sure your flashing is in good condition and there are no soft spots or cracked caulking. Also, make sure you use the right coating. Asphalt or aluminum coatings cannot be used on PVC or rubber (EPDM) roofs.

Gutters are important as well. To avoid winter water damage, be sure to clean out and inspect rain gutters for leaks or holes. They should be slanted so water runs away from your mobile home. Don’t forget to check and repair downspouts or extensions.

4. Know your Home’s Measurements

Mobile homes, built before July 1978, will not use standard ‘big box construction store’ sizes. Bathtubs are usually smaller than those available at Lowe’s or Home Depot. Doors, both interior and exterior, are usually smaller as well. Windows are also typically an odd size.

Here’s a good video that shows you how to measure your mobile home exterior door:

As soon as you can measure everything: cabinets, fridge, stove, windows, doors, tubs, faucets, counters, closets, etc. This way you will always know if that beautiful counter top you found at the flea market will fit.

Make sure doorknobs, faucets and other fixtures are fitted properly. In case you need to change them, take your current hardware along with you to hardware store. Some fixtures for mobile homes are specially designed just for mobile homes.

5. Helpful Plumbing Tips

Mobile home plumbing is a bit different from site-built homes but the same concept applies: the plumbing system has a supply line, a waste or drain line, and ventilation. The pipes have to be able to breath to work properly.

Ideally, all mobile homes will have a shut-off valve at every water feature. If possible, add one to the toilet and faucets in the bathroom and kitchen. Make sure you know where your main shut-off valve is to your home, too.

6. Learn How to Inspect a Mobile Home

While a homeowner inspection should never replace a professional inspector it is smart to do a regular inspection of your home.

Problem is, most of us don’t know what to look for or know when something seems ‘off.’

Here’s a quick list of common issues you should look for when doing a mobile home inspection:

  • Are the I-beams bent or rusted?

  • Is the wood floor framing damaged or rotted?

  • Are the masonry piers cracked, chipped, or otherwise damaged?

  • Are the masonry piers in contact with the steel frame?

  • Are the masonry holes in blocks used in the piers facing upward or sideways?

  • Are wooden wedges present between the pier cap and the steel frame?

  • Is there perimeter blocking located underneath large wall openings such as sliding glass doors and windows greater than 4’ in length?


Your mobile home can last many decades with proper maintenance and care. The maintenance is essentially the same as a stick built home with only a few differences such as skirting and roofing.

As they always say, “an ounce of prevention is better than a pound of cure” (or something like that). A few minutes of inspection time and a couple of dollars in material can save you a lot of time and money in the future.
