Improper installation of carpet can lead to several problems. As a homeowner, you have to do a lot of things for your carpet installation. You can't expect the installer to do everything. You also have some responsibilities.
Before the installation
Ask the installer if they would remove the furniture. Most installers do, but if they don't you have to remove them on their own. Remove all valuables and personal items from the room. All electronic appliances have to be removed.
Turn off the Sprinkler system. The installer will need a dry area to unroll the carpet and cut it. That is why you have to turn off the sprinkler.
Before cutting the carpet, you need to ensure that they have brought the correct carpet. Once it is cut, it is yours.
You must be willing to provide electricity. The installer will need to plug in their electric seaming irons.
If you already have carpet on the floor, the installer will cut it up so that it becomes easier to remove it. If you would like them to haul the old carpet away, you will have to pay an extra charge.
The left overs of the new carpet and padding are usually hauled away by the installer. But if you paid for it, you can keep the leftovers. It is recommended that you keep the leftovers, because they are useful when you have to repair the carpet in the future.
After installation, you need to vacuum. Some installers may offer vacuuming services for an extra charge. Make sure that the installer has trimmed all seams before you vacuum the carpet. Otherwise the vacuuming may pull the yarns and threads. That will damage the carpet.
During carpet installation, your walls may get scuffed up. This is normal.
Make sure that the carpet is trimmed and tucked to base of the wall.
The biggest problem with direct glue installation is the lack of sufficient glue on the floor. The floor and the backing of the carpet have to be entirely covered by the adhesive. If sufficient adhesive is not used, it might result in bubbles. Wait at least 24 hours before walking or moving items on an adhesive installation.
Stapling the carpet to the tackstrip is not recommended. This is something that inexperienced installers do. Instead, a powerstretcher should be used.
Some carpets are not meant for installation on stairs. The retailer should have mentioned this. Once the installation begins, rectifying this problem can be difficult. Carpet is usually constructed in rows and when it is folded around the curves of the stair, the row becomes very noticeable in some designs. If you are planning to install the carpet on stairs, try folding it in the store. This will help you decide whether you will be happy with its folded appearance.
