It sounds from your description that you may be dealing with 2 issues. Allergic rhinitis, or what we all call allergies may be triggered by mold in the home. There are various medicines for this, but you can limit mold in your home with a dehumidifier and possibly a HEPA filter to filter mold spores.
In terms of sensitivities to certain strong odors, this is not a true allergy, but usually something known as "vasomotor rhinitis" or a sensitivity that triggers dilation of blood vessels in the nose and sinuses. It can cause congestion, runny nose, and sneezing just like the allergic variant. Treatment is a bit different and you should speak to your doctor about this.
These two types of rhinitis often are present together.  It may seem that one causes the other, but this is not necessarily true. Good nasal hygiene, use of saline sprays, and occasional decongestants can be helpful for both conditions, but you should see your physician for a full evaluation.
